1. Abstract

The ACV Protocol provides a method for communication between a cryptographic module that is embedded inside of a device or otherwise running on a platform accessible via computer network, and an external testing system, using standard network communication interfaces and protocols. This communication protocol can also be used to validate the correctness of the algorithm implementations in the cryptographic module with a validation authority.

2. Introduction

The Automated Crypto Validation Protocol (ACVP) defines a mechanism to automatically verify the cryptographic implementation of a software or hardware crypto module. It introduces a method to perform cryptographic assessment and validations at a rate which meets typical industry development cycles; providing the ability to deploy validated crypto with CVE fixes much faster than previous methods.

The ACVP specification describes how the protocol is structured with respect to the client-server model, messaging, optional features, and flows. It defines how a crypto module communicates with an ACVP server; including crypto capabilities negotiation, session management, authentication, vector processing and more. The ACVP specification does not define algorithm specific JSON constructs for performing the crypto validation. A series of ACVP sub-specifications define the constructs for testing individual crypto algorithms.

3. Conventions

4. Overview

ACVP has the following goals:

ACVP defines how to communicate a request (to execute a cryptographic operation) to a cryptographic module, and how to communicate the corresponding response (containing the output of that operation) back to a testing system. It defines a transport (based on HTTP or HTTPS [RFC7230]), an JSON message structure(which is negotiated), and a set of message exchanges. Each vector test set corresponds to a single message exchange driven from the client associated with the module under test. ACVP does not define the cryptographic algorithms, nor does it detail the precise conditions for a response to be acceptable. Instead, it references existing specifications for those algorithms, and defines a mapping between the data on the wire and the algorithm testing specification. ACVP does not define detailed conformance criteria, such as those in FIPS-140. Instead, it aims to be independent of particular conformance criteria, so that it can be used in multiple domains with different (even potentially conflicting) conformance criteria. ACVP does not define an interface that can be used to manage or control a cryptographic module.

4.1. Audience

This document is written to address multiple audiences:

  • Crypto module developers who require validation testing
  • Crypto module developers who require runtime crypto assessment testing
  • Crypto validation organizations who will perform validation testing
  • Crypto module customers that desire validation testing results or verifiable artifacts of testing

4.2. Goals

The goals for this document are to provide a messaging protocol that can be used with existing authentication and communication protocols to provide a way to test crypto modules. The following functions are outside the scope of this document:

  • The API to the cryptographic module
  • How the tests are generated
  • How the results/artifacts are stored or managed
  • Authentication used
  • Scalability
  • Management interface

With that in mind there are several expectations when building a server used as a validation authority. A validation authority SHALL use a combination of HTTPS [RFC7230], TLS 1.2 [RFC5246] or greater and mutual authentication. Therefore a client that expects to be used with a validation authority SHALL have the same requirements. A server, proxy or client developed for the purposes of internal organizational testing only MAY choose not to include some of those features.

5. Architecture

A server/client/proxy model is used where the roles are defined as:

5.4. Terminology

The following terms are consistently used throughout this document and SHOULD be used throughout its extensions:

  • Test Session - The largest structure of an instance of ACVP. Often generated from a single registration, it will contain many Test Vector Sets for the algorithms defined in the registration.
  • Test Vector Set - The set of tests and data corresponding to an individual algorithm from within a registration. Uniquely identified throughout an instance of ACVP by the vsId. Contains many Test Groups.
  • Test Group - The set of tests that share common properties within a Test Vector Set. Uniquely identified within the Test Vector Set by the tgId. Contains many Test Cases.
  • Test Case - The smallest unit of the tests that represents an individual testable operation as defined by the parent Test Group. Uniquely identified throughout the Test Vector Set by the tcId.
  • Registration - The JSON from the client to the server that describes the algorithms and capabilities for which the client is seeking test cases and a validation. A Registration can submit capabilities for multiple algorithms. Each algorithm will be broken into individual Test Vector Sets.
  • Request - The JSON sent from the server to the client defining a single Test Vector Set to use as inputs for testing. Exactly one request will exist for each Test Vector Set.
  • Response - The JSON from the client providing the desired cryptographic output for each of the Test Cases defined in the corresponding Request file. These are linked via the Test Vector Set vsId. As exactly one request exists for each vsId, one response will exist for each request.
  • Disposition - The JSON from the server after the Response is submitted by the client detailing the correctness of the Test Cases. A "passed" disposition indicates that the particular algorithm in the Test Vector Set is ready for validation.
  • OE - Operational Environment - The specific hardware and/or software the client's cryptographic implementation uses to run.
  • Realtime - For the purposes of this document realtime is defined as the client receiving a vector set and immediately performing the tests and returning the results to the server. In general, this is a case where the ACVP client and crypto module reside in the same box and directly communicate with each other. Non-realtime would refer to the case where the client may gather vector sets from the server and through some means introduce them to the crypto module gather the results and send them back to the server. In general, this is a case where the device hosting the crypto module cannot communicate directly with the ACVP client.

6. ACV Protocol

The ACV protocol will utilize existing mechanisms for transport coordinated with JSON formatted messaging.

Note that deployments utilizing ACV Proxy server MAY use a different protocol, e.g., HTTP, custom server, context and port number to interact with the DUT.

6.2. HTTP URI Resources

In the table below, any parts of a resource path enclosed in curly braces, { or }, are replaced by an instance of what is described in the braces. For example {testSessionId} could be replaced with 1.

An empty cell for a resource and HTTP Method combination denotes that the server returns an HTTP Status 405 code Method not allowed (405).

Resource GET (read) POST (create) PUT (update) DELETE
/requests Section 12.7.1
/requests/{requestId} Section 12.7.2

/testSessions/{testSessionId}/vectorSets/{vectorSetId}/expected Section 12.17.7 (Optional)

The resource path is appended to the path prefix to form the URI used with an HTTP Method to perform the desired ACVP operation. For example to create a new test session using the "/testSessions" resource is "/acvp/v1/testSessions" (assuming an empty context). To create a new Test Session, the ACVP client would use the following HTTP request-line:

POST /acvp/v1/testSessions HTTP/1.1

Likewise, to request a specific vector set from the server the ACVP client would use the following request-line:

GET /acvp/v1/testSessions/1/vectorSets/1 HTTP/1.1

7. Security Considerations

It is RECOMMENDED that HTTPS and TLS 1.2 or greater be used in order to enforce a secure communication method. Not all environments will have TLS so HTTP with some level of authentication may be the only option.

7.1. Authentication

It is RECOMMENDED that an authentication scheme be used. Typically, a JSON Web Token (JWT) is created by the server upon successful client authentication and returned to the client to use as an authorization mechanism for accessing the server resources - see Section 12.3 below for more information. Depending on the target environment and usage objectives, the authentication can be as weak as basic HTTP authentication or as strong as TLS mutual certificate authentication. Definition of an authentication scheme will not be discussed here, but should be agreed upon between the client and server owning entities including the servers owned by the validation authorities. The Section 10 endpoint will be discussed for the purposes of establishing a test session but how a client is authenticated to the server is not prescribed.

8. Encoding

The encoding used for the request/response messaging will be JSON ([RFC7159]). The data will be identified by: Content-type: application/json In order to allow environment specific extensions to a particular version of the ACV protocol, a top-level JSON keyword, extensions will be used to extend the OE description and/or the capabilities. Extensions MAY be ignored by the ACV server. Vector and vector response data will be JSON encoded.

9. Submission Size Considerations

Some server implementations MAY require alternative handling for submission sizes that exceed resource limitations of the normal workflow for a POST response. Server implementations MUST indicate whether the server requires large submission handling and what the maxmimum value for non-large submissions is within the Section 10 response.

10. Login

A login endpoint is mentioned throughout the document and although how to authenticate is left up to the server the following description is an example of the login endpoint to establish a session and obtain a Section 12.3.1. See Section 13 for more information on how to handle data which exceeds the sizeConstraint in the event the value of largeEndpointRequired is true.

10.1. Request

There are two forms of a login request. There is the initial form which just provides the authentication information without any JWT, and there is a renewal login that allows a user to obtain a new JWT containing the claims from an expired JWT in order to access a resource protected with those claims.

POST /login (Initial)

[
  {"acvVersion": "{acvp-version}"},
  {
    "password": "{password}"
  }
]

POST /login (Renewal)

[
  {"acvVersion": "{acvp-version}"},
  {
    "password": "{password}",
    "accessToken": "{jwt value}"
  }
]

10.2. Response 

[
  {"acvVersion": "{acvp-version}"},
  {
    "accessToken": "{jwt value}",
    "largeEndpointRequired": false,
    "sizeConstraint": -1
  }
]

10.3. Multi Refresh JWT

This endpoint can be utilized for refreshing multiple JWTs with a single POST. Because a JWT with claims is issued for each test session created and clients have the option of performing more than one test session at a time, a mechanism for refreshing multiple JWTs across multiple test sessions simultaneously MAY be made available.

10.3.1. Request

POST /login/refresh

[
  {"acvVersion": "{acvp-version}"},
  {
    "password": "{password}",
    "accessToken": [
      "{jwt1}",
      "{jwt2}",
      "..."
    ]
  }
]

10.3.2. Response 

[
  {"acvVersion": "{acvp-version}"},
  {
    "accessToken": [
      "{newJwt1}",
      "{newJwt2}",
      "..."
    ],
    "largeEndpointRequired": false,
    "sizeConstraint": -1
  }
]

Note the order of JWTs between the request and response is preserved.

11. Versioning

The version of the ACVP protocol will be carried with each message and will contain a simple major.minor format. Major version changes will not be backward compatible, however additions and enhancements that do not disrupt compatibility will be indicated with a minor version change. A server MAY accept a down-level version from the client if it can process at a lower level. If not, it will reject the session. All subsequent messages will carry the negotiated version value.

12. Messaging and Workflow

12.1. Product Registration/Capabilities Exchange

The product registration will utilize the URI resources Section 6.2 to register and provide cryptographic capabilities. This exchange will consist of several message exchanges and will provide a detailed list of cryptographic algorithms and their options to be tested during the testSession, see Section 12.4, Paragraph 2, retrieval of test vectors, submission of test responses, determining test result, and a certification step to associate the product and tested environment information with the completed test. A set URI resources are also available to retrieve and manage the available metadata such as companay name, primary contact, product descriptions, and operational environment descriptions.

12.2. Test Exchange

The test exchange consists of the ACV client requesting a particular vectorSet associated with the testSession. The server responds with the vectorSet. The client MAY retreive and process the vectorSets in order and MAY retreive a vectorSet and immediately return results or request all of the vectorSets and return results at a later time. The client repeats this process until all of the vectorSets in the testSession list have been processed. Once a vectorSet result has been POSTed to the server the client may request success/failure results from the server at any time, however if vectorSets have not been completed the overall status will be incomplete. A minimal message flow is described below Section 12.4, Paragraph 2.

12.3. JSON Web Token (JWT)

JSON Web Token is described in [RFC7519] and is used as an authorization mechanism for gaining access to different resources.

{
    "alg" : "none"
}
{
    "iss" : "nist.gov",
    "nbf": 1598293915,
    "exp": 1598295715,
    "iat": 1598293915,
    "pkey" : "cc74f56acdba635079383a03941d68db55c7b3c2f (truncated)"
}
{

}

The JWT can be secured if desired using the header encryption "alg" value defined to HS256(HMAC-SHA256) or one of the other secure values. Key agreement would follow RFC7518.

{
  "alg": "HS256",
  "typ": "JWT"
}
{
  "iss" : "nist.gov",
  "nbf": 1598293915,
  "exp": 1598295715,
  "iat": 1598293915,
  "pkey" : "cc74f56acdba635079383a03941d68db55c7b3c2f (truncated)"
}
{
    "{signature}"
}

where "{signature}" is made up of:

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  secret)
Figure 6

and where "HMACSHA256" is the algorithm specified in the JWT header.

The first four claims are required, however "pkey" is an optional private claim used to pass the key used for encrypting the database at the server. Enabling this option is discussed further in Section 12.16.2

12.3.1. Authorization flows with JWT

JSON Web Token is described in [RFC7519] and is used as an authorization mechanism for gaining access to different resources.

In order to access any resource which requires authorization a client must supply the JWT as an Authorization header value as a Bearer token. An example header value is:

Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5c (truncated)"

12.3.2. JWT Expiration/Renewal

The JWT access tokens received from either the /login server endpoint SHALL be set to expire after a pre-defined period. The specific length of the expiration period is out of scope for this specification. However, the expiration period length impacts both the security and protocol overhead. Longer expiration periods reduce the overhead but increase the window for attacks. Attempting to access a service with an expired JWT SHALL result in a "401 Unauthorized" HTTP status code.

A client may renew an expired JWT access token using the mechanism shown in Section 12.3.2, Paragraph 3below.

12.5. Paging

Some resource operations require paging in order to avoid returning large amounts of data. Each operation that uses paging will indicate that uses paging and what the value for each element will be within the section describing that operation. All paged responses MUST follow the format described in Section 12.5.2. Conversely, clients may navigate pages using the paging parameters described in Section 12.5.1. Server implementations SHOULD impose limitations on the page size limit based on resource constraints.

12.5.1. Parameters

A Server MUST accept requests without paging parameters. If not all results are returned, the response MUST indicate that not all of the results were provided using the incomplete property of a paged response described in Section 12.5.2. The query parameters clients MUST use to specify paging are described below:

  • limit - number, the maximum number of entries to return. Server implementations MUST allow requests without a provided value, but the default value is a choice for server implementations.
  • offset - number, the offset into the list of entries, MUST default to 0 if not provided.

GET /acvp/v1/vendors?offset=20&limit=20 HTTP/1.1

12.5.2. Response

A paged response has the following properties:

  • totalCount - number, the total number of resources available to return
  • incomplete - boolean, true if more resources are avaiable than what is returned in the response

  • links - object, links to use when navigating the pages

    • first - string, a link to the first page in the result set
    • next - string, a link to the next page in the result set, null if no next page is available
    • prev - string, a link to the previous page in the result set, null if no previous page is available
    • last - string, a link to the last page in the result set
  • data - array, contains an array of data appropriate to the resource requested 
[
    {"acvVersion": <acvp-version>},
    {
        "totalCount" : 22007,
        "incomplete" : true,
        "links" : {
            "first" : "/acvp/v1/<resource>?offset=0&limit=20",
            "next" : "/acvp/v1/<resource>?offset=20&limit=20",
            "prev" : null,
            "last" : "/acvp/v1/<resource>?offset=22000&limit=20"
        },
        "data" : [ <resource response> ]
    }
]
Figure 13

12.6. Query Parameters

Some of the resource listing operations allow for query parameters to be provided to filter out the returned values. Each resource will list what properties and operations are available but the general format of the query parameter string is consistent across all resources. The format allows for the specification of complex filters with the concept of groups, where all elements in the same group MUST be AND'ed together and different groups are OR'ed together. The URL including the parameter values MUST conform to [RFC3986] and MUST use UTF-8 character encoding.

General format of a query parameter element.

<property>[<index>]=<operation>:<value>
Figure 14
  • property - is the property to be specified
  • index - is an arbitrary group index, elements with same group index are AND'ed together and elements with different indices are OR'ed togther. index MUST be between 0 and 99 inclusive.

  • operation - is an operation on a property and a value. Not all operations require a value, and not all properties will permit every operation. Available operations are:

    • eq - filter based on property equal to the value
    • ne - filter based on the property not equal to the value
    • gt - filter based on the property greater than the value
    • ge - filter based on the property greater than or equal to the value
    • lt - filter based on the property less than the value
    • le - filter based on the property less than or equal to the value
    • contains - filter based on the property containing the value
    • start - filter based on the property starting with the value
    • end - filter based on the property ending with the value
  • value - the value to filter on, it MAY be constrained based on the property

Example 1

/resource?property1[0]=eq:foo&property2[0]=eq:foo
&property1[1]=eq:test&property2[1]=ne:bar
Figure 15

For the example above the results returned would include resources that have: property1 equal to foo and property2 equal to foo or resources that have property1 equal to test and property2 not equal to bar.

Example 2 based on Section 12.8.1.

/vendors?name[0]=contains:acme&name[1]=contains:test
Figure 16

For the example above the vendor results returned would include resources that have a name property value that contains either acme or test.

12.7. Requests

Some resource operations make a request to modify or create data. To facilitate an out-of-band approval step, where data can be inspected to insure it meets the business requirements of the validation authority which operates the server, the operations will return a request url that can be used to obtain information about the status and disposition of the requested modification. Whether or how an authority implements an approval step is outside the scope of this specification.

A request resource is not externally updateable, but SHOULD update based on server processing. The properties for a request response:

  • url - string, identifier for this resource

  • status - string, one of:

    • initial - initial state of the request, created
    • processing - server is processing the request
    • approved - the requested operation was successfully processed
    • rejected - the requested operation was rejected and no change was made
  • message - string, a placeholder for any message describing a rejection
  • approvedUrl - string, a link to the resource which was created or modified as a result of the requested operation

If the server did not have enough time to generate the vector set for a given test session, the server may reply:

[
  { "acvVersion": "{acvp-version}" },
  { "vsId": 1,
    "retry" : 30
  }
]

Where:

  • retry - represents the number of seconds for the client to wait before retrying the request.

The server may set the retry value based on the current server load and expected processing time to generate the vector set.

12.17.3. Cancel Testing of a Vector Set

DELETE /testSessions/{testSessionId}/vectorSets/{vectorSetId}

Cancel testing for a specific Vector Set.

There may be cases where a particular vector set may not be cancelled and the entire Test Session will need to be cancelled instead.

12.17.4. Request Validation Results

GET /testSessions/{testSessionId}/vectorSets/{vectorSetId}/results

Request Validation Results for a Vector Set.

When showExpected was set to true from a POST/PUT under Section 12.17.5, additional information is provided back to the client for any failing test cases. The additional information includes an "expected" as well as "provided" object that MAY be useful in diagnosing issues within the vector set validation.

12.17.4.1. Response

The client will send this request to learn the validation results for an individual vector set. Properties are:

  • vsId - number

  • disposition - string, the overall result for the vector set with:

    • fail - indicates at least one test case has failed.
    • unreceived - indicates the server has not received responses from the client for all the test cases.
    • incomplete - indicates not all tests have been processed by the server, however none have failed thus far.
    • expired - indicates not all the test case responses were received from the client prior to expiry.
    • passed - indicates all test cases have been processed by the server and have passed.
    • missing - indicates that one or more test case responses were not received from the client.
    • error - indicates that the server encountered an error while processing the responses provided by the client.

  • tests - array of test result objects

    • tcId - number

    • result - string, the result for a test case with:

      • fail - indicates the test case has failed.
      • unreceived - indicates the server has not received a response from the client for the test case.
      • incomplete - indicates the server has not processed the test case.
      • expired - indicates the client did not send the test case response to the server prior to expiry.
      • passed - indicates the test case passed.
      • missing - indicates that a response was not received from the client for the test case.
    • reason - string, provides additional detail in case of a failed result value.
    • expected - object, provides the value(s) the server expected for the test case.
    • provided - object, provides the value(s) the client provided for the test case.

    }}
]

12.17.5. Submit Results

POST /testSessions/{testSessionId}/vectorSets/{vectorSetId}/results

Initial Submission of Vector Set Test Results.

12.17.5.1. Request

The client will send this request to submit the test results for an individual vector set. Similar to the vector set download the format will vary depending on the specific sub-specification of the algorithm and testType being tested.

[
  {"acvVersion": "{acvp-version}"},
  {
    "vsId": 1437,
    "revision": "1.0.0",
    "showExpected": true,
    "testGroups": [{
      "tgId": 1,
      "tests": [{
          "tcId": 12340,
          "testCaseProperty1": "ABCD",
          "testCaseProperty2": "1234"
        },
        {
          "tcId": 12341,
          "testCaseProperty1": "5678",
          "testCaseProperty2": "FEDC"
        }, ...
      ]
    }, ...
    ]
  }
]

The showExpected property is optional; when included (and set to true) the ACVP server will include additional information within the validation response file described in Section 12.17.4.

12.17.5.2. Response

No content response. Standard HTTP status codes will indicate success or failure of the submission, but do not indicated the disposition of the tests.

12.17.6. Update Results Submission

PUT /testSessions/{testSessionId}/vectorSets/{vectorSetId}/results

Update Vector Set Test Results Submission.

When one or more test cases fails, the client will need to correct the issue in the crypto module and send the responses again. The resending of responses for failed test cases will occur for an entire vector set. Therefore, even if only a single test case in the vector set failed, the client will need to download, process, and upload responses to the server for the entire vector set (presumably after the problem has been corrected in the implementation). The resending of vector set responses MUST occur prior to expiry.

12.17.6.1. Request

The request content is identical to the request content described in Section 12.17.5.

12.17.7. Retrieve Expected Results

GET /testSessions/{testSessionId}/vectorSets/{vectorSetId}/expected

Expected Test Results. Expected test results SHALL be generated by the server if the isSample test session resource equals true. See Section 12.16.

12.17.7.1. Response

The response is identical to the request content described in Section 12.17.5.

13. Large Submission

When clients have a response which exceeds the sizeConstraint in Section 10, this endpoint MUST be used to obtain a URI in order to submit the results. The URI MAY be a one-time use URI and clients SHOULD only attempt to use this URI once regardless of success or failure in submitting. If resubmission is required clients MUST re-POST to the /large endpoint in order to obtain the URI to use.

The available properties for large submissions:

13.1. Request

POST /large

[
  {"acvVersion": "{acvp-version}"},
  {
      "submissionSize": 5000000,
      "vectorSetUrl" : "/acvp/v1/testSessions/1/vectorSets/10"
  }
]

13.2. Response 

[
  {"acvVersion": "{acvp-version}"},
  {
      "url": "https://acvts.authority.org:3954/large/QWERTY123",
      "accessToken" : "<jwt token>"
  }
]

14. Vector Set Expiration

Vector sets can expire. For example, in terms of a validation authority use, the vector sets are one-time use only. Old vector sets can never be reused to obtain a new validation certificate for an algorithm implementation or to update an existing certificate. Expiration is a server specific definition which depends on database costs, need for artifacts, etc. If the vector set has expired, the server will reply with an expired response when the client attempts to download the vector set:

[
    {"acvVersion": "{acvp-version}"},
    {
        "vsId": 42,
        "status": "expired"
    }
]

The ACVP protocol requires server implementations to generate test values and retain the data while the ACVP client processes and returns the results. Some crypto modules implementing the client-side ACVP protocol may not return results immediately. The ACVP protocol design implies the server must retain the test values to verify the client test responses at some time in the future. However, some test vector sets are fairly large, which could place significant storage requirements on ACVP server implementations. To alleviate long term storage requirements, ACVP allows for an expiration timestamp to be set when a test vector set is generated by the server.

The vector set expiration timestamp must be included by the server in the vector set when the client downloads the vector set. The server may change the expiration timestamp of a previously issued vector set to extend its lifetime subject to server policy. The expiration timestamp must be in the 'expiry' JSON value, which is included in the JSON encoded vector set. The expiry JSON value will be a string value of the UTC timestamp using form "YYYY-MM-DD HH:MM:SS". The following figure shows a partial JSON encoded vector set that contains the expiry value.

[
    {"acvVersion": "{acvp-version}"},
    {
        "vsId": 1437,
        "expiry": "2018-12-31 23:59:59",

                "testType": "type1",
                "tests": [
                    {
                        "tcId": 1,
                        "testCaseProperty1": 1,
                        "testCaseProperty2": "2"
                    },
                    {
                        "tcId": 2,
                        "testCaseProperty1": 3,
                        "testCaseProperty2": "4"
                    },
            .
            .
            .
            <remainder of vector set omitted from figure>
            .
            .
            .
            ]
        }]
    }
]

15. Error Codes

Errors will follow HTTP[S] numbering scheme. In addition errors as well as 200 messages may carry JSON encoded information that describes in detail the error and any associated troubleshooting information. Examples of client and server error messages are in Appendix B.

16. Algorithm Test Extensions

ACVP is intended to be an extensible protocol that supports testing of a large number of cryptographic algorithms from several different classes defined by the community. All algorithm identifiers intended for public use SHALL be documented by IANA in the ACVP IANA Registry [acvp-iana].

To add testing for a new algorithm first try to find an algorithm of the same type that is already supported by the protocol.

If it belongs to an already-supported type, check the test specification for the similar algorithm. Typically, similar algorithms share similar testing methodology.

For example, the testing of symmetric block ciphers is comprised of two test types: Algorithm Functional Tests and Monte Carlo Tests - see [sub-symmetric].

Assuming that the existing test types provide sufficient test coverage for the new algorithm, one needs to add the new block cipher algorithm to the symmertic block cipher specification [sub-symmetric], including the JSON schema for the corresponding test data exchanges between the validation server and the client. See in particular Section "Adding new algorithms" in the corresponding algorithm specification.

Next, one needs to update the IANA registry with the new algorithm by adding it to the corresponding namespace and subject to the policies stated in [acvp-iana].

Once this is completed and the corresponding server test generation and validation for that algorithm are implemented, testing can commence. Clients implementing that algorithm may register it for testing as described in Section "Capabilities Registration" in [sub-symmetric], process the test vectors generated by the validation server and return the results for validation.

If the available test types for an algorithm, existing or new, in a given class do not provide good test coverage of the algorithm, one could develop a new test type and incorporate it into the corresponding test specification for the that algorithm. See for example Section "Adding new algorithms" in [sub-symmetric] for how to add a new test type. Note that this action would require modifications of the corresponding algorithm test specification and would result in a new version of that test specification to be reflected in the IANA registry [acvp-iana].

17. Custom Specification Objects

17.1. Date

A date type is a time string formatted according to the rules of [RFC3339]; all date/times must use UTC time denoted by 'Z' suffix with no local timezone adjustment. Example is 2018-06-01T20:10:33Z

17.2. BitString

Bitstrings are used to communicate a string of bits between the ACVP server and IUT.

17.2.1. Endianness

BitStrings SHALL be considered in big endian order, unless otherwise specified by the algorithm.

The hex string "FA" (assuming all bits are considered) SHALL represent the bits 11111010 (in MSb) or the value 250.

17.2.2. Hex to Bitstring Parsing

"valueLen" will be used as the example, but it can apply to any bit length registration/vector set/etc parameters.

When a "value" is provided along with a "valueLen", the "valueLen" MUST be considered when parsing the hex string represented in "value", EXCEPT in empty bitstring cases, which MUST be represented as an empty string "". Parsing Hex strings into Bit strings is especially important for algorithms such as the SHA variations that may only include a portion of bits from the provided hex string. When only a portion of bits from a Hex string are considered, bits for use in the bitstring SHALL be taken from the most significant bits, meaning the lesser significant bits are the bits that are dropped.

17.2.2.1. Hex string parsing examples
  • valueLen: 8, value: "FA", SHALL be parsed as the bits 11111010, or the value 250.
  • valueLen: 7, value: "FA", SHALL be parsed as the bits 1111101, or the value 125.
  • valueLen: 5, value: "FA", SHALL be parsed as the bits 11111, or the value 31.
  • valueLen: 3, value: "FA", SHALL be parsed as the bits 111, or the value 7.
  • valueLen: 0, value: "", SHALL be interpreted as an empty bit string.

17.3. Range

The Range object can be used to convey a range of values. It contains its own set of properties made up of "min", "max", and "increment". "inc" may be used as a shorthand for "increment." If the "increment" property is omitted, a default value of 1 SHALL be used.

17.3.1. Range JSON examples

A range object specifying a minimum of 1, a maximum of 8, with an increment of 1. This range object includes the values 1, 2, 3, 4, 5, 6, 7, and 8.

{"myRange": {
    "min": 1,
    "max": 8,
    "increment": 1
}}

A range object specifying a minimum of 0, a maximum of 8, with an increment of 2. This range object includes the values 0, 2, 4, 6, and 8.

{"myRange": {
    "min": 0,
    "max": 8,
    "increment": 2
}}

17.4. Domain

The Domain object can be used to specify a set of values similar to Range, albeit with more control. A domain can be made up of an array of objects, where those objects can be literal values, and/or Range objects.

17.4.1. Domain JSON examples

Several sample domain objects that state 0, 8, 16, 32, 96, 128, 192, and 256 are valid values.

{"myDomain": [
    {
        "min": 0,
        "max": 16,
        "increment": 8
    },
    32,
    96,
    {
        "min": 128,
        "max": 256,
        "increment": 64
    }
]}
{"myDomain": [ 0, 8, 16, 32, 96, 128, 192, 256 ]}

17.4.2. Additional Domain Information

Because the Domain is an array of objects consisting of (potentially) both literals and ranges, algorithms that use an array of integers can be used interchangably with the Domain object.

18. IANA Considerations

This document does not require any action by IANA.

19. Other Considerations

When an ACVP client is attached to a cryptographic module that is in use, access to ACVP MUST be controlled so that only an administrator or other authorized user can send and receive ACVP messages. This is because an attacker that has access to ACVP can potentially use it to probe for weaknesses in the cryptographic module.

21. JSON Formatting Guidelines

All JSON keywords SHALL use lower camelCase format with no underscores or hyphens and use the following characters only a-z, A-Z, 0-9. Keywords SHALL abbreviate common words and phrases wherever possible for brevity.

For example: password length - pwLen plain text length - ptLen

Keywords SHOULD be chosen such that they are informative and brief, for example:

[
    { "acvVersion": "{acvp-version}" },
    { "results" : { "disposition" : "incomplete" } }
]

Metadata assigned to the keyword may use any format which best reflects the information being represented including hyphens, underscores alternating case, numbers, etc. However, brevity should be a major consideration, for example:

{
    "algorithms" : [
        { "algorithm" : "ACVP-AES-GCM", "mode" : "modes", "ivGen" : "internal", "ivGenMode" : "8.2.1" }
    ]
}

All metadata representing strings or big numbers SHALL use double quotes at both ends. Big numbers require conversion from strings to whatever format is used by the DUT. Numerical values of integer size or with decimal points may use quotations if those values are generally used as a string, for example the acvVersion would generally be used in displaying information not in any mathematical operations. Something like keyLen or ptLen values would be better used without quotes to avoid having to convert the string to an integer for use in the code.

22. Error Messages

General or registration errors detected by the server SHALL result in an HTML error and description of the problem, for example:

    HTTP response: 400
    "error" : "Incorrectly formatted JSON (51:18):
               expected field name was not provided: inBit"
Figure 17

Errors detected by the client SHOULD trigger an indication of the operation that failed and a detailed error description. This information can be sent to the clients local logging facility to provide traceability of communication issues, for example:

    ACV Operation: SHA-512
    Error: Unsupported hash algorithm
Figure 18
