2. Abstract

This document defines the JSON schema for testing RSA implementations with the ACVP specification.

3. Introduction

The Automated Crypto Validation Protocol (ACVP) defines a mechanism to automatically verify the cryptographic implementation of a software or hardware crypto module. The ACVP specification 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. Each sub-specification addresses a specific class of crypto algorithms. This sub-specification defines the JSON constructs for testing RSA implementations using ACVP.

  • RSA / decryptionPrimitive / Sp800-56Br2

6. Test Types and Test Coverage

This section describes the design of the tests used to validate RSA implementations.

6.1. Test Types

There are multiple test types depending on the algorithm and mode. Each has a specific value to be used in the testType field. The testType field definitions are:

"AFT" - Algorithm Functional Test. These tests can be processed by the client using a normal 'generate_key', 'sign', 'verify' or 'decrypt' operation depending on the mode. AFTs cause the implementation under test to exercise normal operations. In all cases, random data is used. The functional tests are designed to verify that the logical components of the process are operating correctly.

"GDT" - Generated Data Test. These tests require the client to generate all inputs and outputs in order to demonstrate their full capabilities in cases where input from the server might not be applicable.

"KAT" - Known Answer Test. These tests are staticly defined and are included in every vector set that matches their capabilities.

6.2. Test Types Per Mode

As each mode requires different tests, how each test type is processed may change depending on the mode.

ACVP servers that support RSA keyGen MAY support AFTs, GDTs, and KATs. The AFTs and GDTs REQUIRE the client to generate RSA key pairs based on the test group properties provided. The KATs REQUIRE the client to attempt to generate a key with specific starting 'p' and 'q' values via the Random Probable Prime method defined in [FIPS186-4] and [FIPS186-5].

ACVP servers that support RSA sigGen MAY support GDTs. The GDTs REQUIRE the client to generate a key pair and sign a message provided by the server based on the test group properties provided. The client provides the signature and public key to the server for verification.

ACVP servers that support RSA sigVer MAY support GDTs. The GDTs REQUIRE the client to verify provided signatures given a message and public key. The client provides the verification result back to the server.

ACVP servers that support RSA LegacysigVer MAY support GDTs. The GDTs REQUIRE the client to verify provided signatures given a message and public key. The client provides the verification result back to the server.

ACVP servers that support RSA SignaturePrimitive MAY support AFTs. The AFTs REQUIRE the client to determine whether or not the provided message can be signed with the provided public key. If so, also provide the signature for verification.

ACVP servers that support RSA DecryptionPrimitive MAY support AFTs. The AFTs REQUIRE the client to determine whether or not the provided ciphertext can be decrypted with the provided public key. If so, also provide the plaintext for verification.

6.3. Test Coverage

The tests described in this document are intended to ensure an implementation conformant with the requirements listed below. For clarity, related requirements not covered are also provided.

6.3.1. Requirements Covered

  • FIPS 186-4 Section 3 General Discussion. Key generation, signature generation, and signature validation are all within scope of ACVP server testing.
  • FIPS 186-4 Section 5 The RSA Digital Signature Algorithm. The ACVP server provides a means of testing the generation of RSA keys. The ACVP server SHALL support a variety of RSA capabilities functionS for the creation and delivery of tests to/from the IUT. Key pair generation testing SHALL be provided by the ACVP server. Both Signature Generation and Validation testing mechanisms SHALL be provided by the ACVP server.
  • FIPS 186-2. The ACVP server MAY provide a means of testing legacy RSA functions such as RSA sigVer. This testing is provided to ensure an IUT is capable of verifying a signature that is no longer approved for generation, given the same capabilities.
  • SP800-106 Section 3 Randomized Hashing and Section 4 Digital Signatures Using Randomized Hashing. The IUT SHALL be provided or provide a random value that should be used to "randomize" a message prior to signing and/or verifying an original message.

6.3.2. Requirements Not Covered

  • FIPS 186-4 Section 3 General Discussion. Assurances of private key secrecy and ownership SHALL NOT be within scope of ACVP testing.
  • FIPS 186-4 Section 5 The RSA Digital Signature Algorithm. Though the ACVP server SHALL support a variety of parameter sizes hash functions, the IUT's selection of these is out of scope of testing. Key pair management SHALL NOT be within scope of ACVP testing.
  • SP800-106 Section 3.3 The Random Value. DSA, ECDSA, and RSA have random values generated as per their signing process, this random value can be used as the input to the message randomization function, doing so however is out of scope of this testing.

7. Capabilities Registration

ACVP requires crypto modules to register their capabilities. This allows the crypto module to advertise support for specific algorithms, notifying the ACVP server which algorithms need test vectors generated for the validation process. This section describes the constructs for advertising support of RSA algorithms to the ACVP server.

The algorithm capabilities MUST be advertised as JSON objects within the 'algorithms' value of the ACVP registration message. The 'algorithms' value is an array, where each array element is an individual JSON object defined in this section. The 'algorithms' value is part of the 'capability_exchange' element of the ACVP JSON registration message. See the ACVP specification [ACVP] for more details on the registration message.

7.1. Prerequisites

Each algorithm implementation MAY rely on other cryptographic primitives. For example, RSA Signature algorithms depend on an underlying hash function. Each of these underlying algorithm primitives must be validated, either separately or as part of the same submission. ACVP provides a mechanism for specifying the required prerequisites:

Prerequisites, if applicable, MUST be submitted in the registration as the prereqVals JSON property array inside each element of the algorithms array. Each element in the prereqVals array MUST contain the following properties

Table 2: Prerequisite Properties
JSON Property Description JSON Type
algorithm a prerequisite algorithm string
valValue algorithm validation number string

A "valValue" of "same" SHALL be used to indicate that the prerequisite is being met by a different algorithm in the capability exchange in the same registration.

An example description of prerequisites within a single algorithm capability exchange looks like this

"prereqVals":
[
  {
    "algorithm": "Alg1",
    "valValue": "Val-1234"
  },
  {
    "algorithm": "Alg2",
    "valValue": "same"
  }
]

7.2. Required Prerequisite Algorithms for RSA Validations

Each RSA implementation relies on other cryptographic primitives. For example, RSA keyGen often uses an underlying SHA algorithm. Each of these underlying algorithm primitives must be validated, either separately or as part of the same submission. ACVP provides a mechanism for specifying the required prerequisites:

Table 3: Required RSA Prerequisite Algorithms JSON Values
JSON Value Description JSON type Valid Values
algorithm a prerequisite algorithm string SHA, DRBG
valValue algorithm validation number string Actual number or "same"
prereqAlgVal prerequisite algorithm validation object with algorithm and valValue properties See above

7.3. RSA Algorithm Registration Properties

Each RSA algorithm capability advertised is a self-contained JSON object using the following values.

Table 4: RSA Algorithm Capabilities JSON Values
JSON Value Description JSON type Valid Values
algorithm The RSA algorithm to be validated string See Section 5
mode The mode to be validated string See Section 5
revision The algorithm testing revision to use string See Section 5
prereqVals Prerequisite algorithm validations array of prereqAlgVal objects See Section 7.2
capabilities The individual RSA capabilities array of capability objects See Section 7.4, Section 7.6, Section 7.7, Section 7.9, or Section 7.8
infoGeneratedByServer This flag indicates that the server is responsible for generating inputs for Key Generation tests boolean true/false
pubExpMode Supports fixed or random public key exponent e string "fixed" or "random"
fixedPubExp The value of the public key exponent e in hex if pubExpMode is "fixed" hex
keyFormat The preferred private key format. The "standard" format has "p", "q", and "d" as the components of the private key. The "crt" (Chinese Remainder Theorem) format has "p", "q", "dmp1" (d modulo p-1), "dmq1" (d modulo q-1), and "iqmp" (inverse q modulo p) as the components string "standard" or "crt"

7.8. RSA SignaturePrimitive Mode Capabilities

The RSA signaturePrimitive mode capabilities (otherwise known as RSASP1 in [RFC3447]) are advertised as JSON objects within the array of 'capabilities' as part of the 'capability_exchange' element of the ACVP JSON registration message. See the ACVP specification for details on the registration message. In this mode, the only tested capability is the correct exponentiation of 's = msg^d mod n', where 'msg' is a message between '0' and 'n - 1', 'd' is the private exponent and 'n' is the modulus, all supplied by the testing ACVP server. In the event that 'keyFormat' is defined as 'crt', then 'd' is replaced with 'dmp1', 'dmq1', and 'iqmp'. For RSA / SignaturePrimitive / 1.0, only 2048-bit RSA keys are allowed for this capability. For RSA / SignaturePrimitive / 2.0, 2048-bit, 3072-bit, and 4096-bit modulus sizes are supported. See Section 8.7 for additional details on constraints for 'msg' and 'n'. See the ACVP specification for details on the registration message.

The following RSA / SignaturePrimitive / 1.0 capabilities MAY be advertised by the ACVP compliant crypto module:

Table 12: Supported RSA SignaturePrimitive 1.0 JSON Values
JSON value Description JSON type Valid values
keyFormat The format by which the client expects the private key to be communicated. Standard refers to the default p, q, d values. Chinese Remainder Theorem uses decomposed values for optimized decryption p, q, dmp1, dmq1, iqmp string "standard", "crt"
pubExpMode Whether the IUT can handle a random or fixed public exponent string "random", "fixed"
fixedPubExp The fixed public exponent e hex Any value supported by [FIPS186-4]: 65537 - 2^256-1, odd

The following is an example of the registration

{
    "algorithm": "RSA",
    "mode": "signaturePrimitive",
    "revision": "1.0",
    "keyFormat": "crt",
    "pubExpMode": "fixed",
    "fixedPubExp": "010001"
}

The following RSA / SignaturePrimitive / 2.0 capabilities MAY be advertised by the ACVP compliant crypto module:

Table 13: Supported RSA SignaturePrimitive 2.0 JSON Values
JSON value Description JSON type Valid values
modulo supported RSA moduli for signature generation - see [FIPS186-4], Section 5 array of integer any of the supported modulus sizes {2048, 3072, 4096}
keyFormat The format by which the client expects the private key to be communicated. Standard refers to the default p, q, d values. Chinese Remainder Theorem uses decomposed values for optimized decryption p, q, dmp1, dmq1, iqmp array of string "standard", "crt"
pubExpMode Whether the IUT can handle a random or fixed public exponent string "random", "fixed"
fixedPubExp The fixed public exponent e hex Any value supported by [FIPS186-4]: 65537 - 2^256-1, odd

The following is an example of the registration

{
    "algorithm": "RSA",
    "mode": "signaturePrimitive",
    "revision": "2.0",
    "pubExpMode": "fixed",
    "fixedPubExp": "010001"
    "keyFormat": [
        "standard",
        "crt"
    ],
    "modulo": [
        2048,
        3072,
        4096
    ]
}

7.9. RSA DecryptionPrimitive v1.0 Mode Capabilities

Note: RSA DecryptionPrimitive v1.0 should be used for PIV card testing, and RSA DecryptionPrimitive Sp800-56Br2 for comforming to Sp800-56Br2 requirements.

The RSA decryptionPrimitive mode capabilities are advertised as JSON objects within the array of 'capabilities' as part of the 'capability_exchange' element of the ACVP JSON registration message. A single property is allowed in the registration, 'modulo' with the only approved value of 2048. In this mode, the only tested capability is the correct exponentiation 's = cipherText\^d mod n', where 'cipherText' is a cipherText to be decrypted, 'd' is the private exponent and 'n' is the modulus. See [SP800-56B], Section 7.1.2 for details.

In testing, only 'cipherText' is supplied by the ACVP server. The client is responsible for generating RSA key pairs of modulus 'n', private key 'd', and calculates 's'. If a client does not support decryption with a standard RSA private exponent 'd', the equivalent Chinese Remainder Theorem (CRT) private key values are allowed to be used. Only 2048-bit RSA keys are allowed for this capability.

See Section 8.11 for additional details on constraints for 'cipherText' and 'n'. The client provides the public exponent 'e', modulus 'n' and the computed result 's' in its response to the ACVP - see Section 9.5. The client must first check if '0 < cipherText < n-1' and return an error if this is not the case. The client returns a value 's' only when 'cipherText' is in the proper range for the size of the selected modulus 'n'. See the ACVP specification for details on the registration message.

An example registration is the following

{
    "algorithm": "RSA",
    "mode": "decryptionPrimitive",
    "revision": "1.0",
    "prereqVals":
    [
        {"algorithm": "DRBG", "valValue": "123456"},
        {"algorithm": "DRBG", "valValue": "654321"},
        {"algorithm": "SHA", "valValue": "7890"}
    ]
}

7.10. RSA DecryptionPrimitive SP800-56Br2 Mode Capabilities

The RSA decryptionPrimitive mode capabilities are advertised as JSON objects within the array of 'capabilities' as part of the 'capability_exchange' element of the ACVP JSON registration message. Two properties are supported in the registration. A 'modulo' array supports three modulus values of 2048, 3072, and 4096. For private 'keyFormat', the "standard" and "crt" (Chinese Remainder Theorem) private key formats are supported. "standard" equates to the prime-factor private key format described in [SP800-56Br2]. See the descriptions of basic, CRT, and prime-factor private key formats in Section 3.2 of [SP800-56Br2].

When testing the "standard"/prime-factor private key format, a ciphertext (ct), along with private key p, q and d component values are provided, see [SP800-56Br2], Section 7.1.2.2 for details. If an IUT supports the basic private key format, the p and q values provided by the "standard"/prime-factor testing can be multiplied to produce the needed n value. When testing for the Chinese Remainder Theorem private key format, a ciphertext (ct), the p, q, n, dmp1 (dP), dmq1 (dQ), and iqmp (qInv) values are provided, see [SP800-56Br2], Section 7.1.2.3 for details. See the ACVP specification for details on the registration message.

Support was added for fixed public exponents, this is done through two settings, 'pubExpMode' and fixedPubExp'. When 'pubExpMode' is set to 'fixed', a 'fixedPubExp' is required. An omitted pubExpMode will default to random.

8. Test Vectors

The ACVP server provides test vectors to the ACVP client, which are then processed and returned to the ACVP server for validation. A typical ACVP validation session would require multiple test vector sets to be downloaded and processed by the ACVP client. Each test vector set represents an individual crypto algorithm, such as RSA / sigGen / FIPS186-4, RSA / keyVer / FIPS186-5, etc. This section describes the JSON schema for a test vector set used with RSA crypto algorithms.

The test vector set JSON schema is a multi-level hierarchy that contains meta data for the entire vector set as well as individual test vectors to be processed by the ACVP client. The following table describes the JSON elements at the top level of the hierarchy.

Table 15: RSA Vector Set JSON Object
JSON Value Description JSON type
acvVersion Protocol version identifier string
vsId Unique numeric identifier for the vector set integer
algorithm Algorithm defined in the capability exchange string
mode Mode defined in the capability exchange string
revision Protocol test revision selected string
testGroups Array of test group JSON objects, which are defined in Section 8.1, Section 8.3, Section 8.5, Section 8.7 or Section 8.11 array

An example of this would look like this

{
  "acvVersion": "version",
  "vsId": 1,
  "algorithm": "Alg1",
  "mode": "Mode1",
  "revision": "Revision1.0",
  "testGroups": [ ... ]
}

8.1. RSA keyGen Test Groups JSON Schema

The testGroups element at the top level in the test vector JSON object is an array of test groups. Test vectors are grouped into similar test cases to reduce the amount of data transmitted in the vector set. The Test Group JSON object contains meta data that applies to all test vectors within the group. The following table describes the RSA / keyGen / * JSON elements of the Test Group JSON object.

Table 16: RSA keyGen Test Group JSON Object
JSON Value Description JSON type
tgId Numeric identifier for the test group, unique across the entire vector set integer
modulo RSA modulus size integer
hashAlg the hash algorithm string
primeTest Miller-Rabin constraint bound string
randPQ keyGen mode used string
infoGeneratedByServer Whether or not the test inputs are generated by the server boolean
keyFormat The RSA private key format used string
pubExp Fixed or random public exponent e string
testType Describes the operation the client should perform on the test data string
tests Array of individual test cases, see Section 8.2 array

The 'tgId', 'testType' and 'tests' objects MUST appear in every test group element communicated from the server to the client as a part of a prompt. Other properties are dependent on which 'testType' (see Section 6) the group is addressing.

The impact of the 'infoGeneratedByServer' property depends on the other properties identified in the keyGen registration. For 'randPQs' of B.3.2, B.3.4, B.3.5, and B.3.6 (or the corresponding FIPS186-5 values), 'infoGeneratedByServer' set to true will provide the client with ALL the inputs and expect them to arrive at the same output the server has already arrived at.

In the case of 'infoGeneratedByServer' being set to false during the registration, the client will be provided with SOME of the inputs, like an already agreed upon fixed public exponent. However, in general the server will send mostly empty test cases. It is the responsibility of the client to generate both the input properties and output properties comprising the test cases and communicate ALL of those back to the server. The server will try to reach the same output key.

For B.3.3 (or the corresponding FIPS186-5 value of probable), 'infoGeneratedByServer' set to true enables the KAT test groups if the client supports a random public exponent. The GDT are always enabled as a bare minimum test for B.3.3 (or probable), independent of the 'infoGeneratedByServer' setting.

8.2. RSA keyGen Test Case JSON Schema

Each test group contains an array of one or more test cases. Each test case is a JSON object that represents a single test vector to be processed by the ACVP client. The following table describes the JSON elements for each RSA / keyGen / * test vector.

The difference between revision "FIPS186-4" and "FIPS186-5" within the prompts lies in the strings used by the server to refer to the various "randPQ", and "primeTest" modes.

8.13. Test Groups for RSA Decryption Primitive Sp800-56Br2

The testGroups element at the top level in the test vector JSON object is an array of test groups. Test vectors are grouped into similar test cases to reduce the amount of data transmitted in the vector set. For instance, all test vectors that use the same key size would be grouped together. The Test Group JSON object contains meta data that applies to all test vectors within the group. The following table describes the RSA JSON elements of the Test Group JSON object

Table 28: RSA Decryption Primitive Sp800-56Br2 Test Group Properties
JSON Values Description JSON Type
tgId Test group identifier integer
modulo The modulo to use in the current test integer
keyMode The mode to be used in current test (aft, crt) string
testType Describes the operation the client should perform on the tests data string
pubExpMode Supports fixed or random public key exponent e (random default if empty) string
"fixed" or "random" fixedPubExp The value of the public key exponent e in hex if pubExpMode is "fixed"
hex tests

The 'tgId', 'testType' and 'tests' objects MUST appear in every test group element communicated from the server to the client as a part of a prompt. Other properties are dependent on which 'testType' (see Section 6) the group is addressing.

8.14. Test Cases for RSA Decryption Primitive Sp800-56Br2

Each test group contains an array of one or more test cases. Each test case is a JSON object that represents a single test vector to be processed by the ACVP client. The following table describes the JSON elements for each RSA / DecryptionPrimitive / Sp800-56Br2 test vector.

Table 29: RSA Decryption Primitive Sp800-56Br2 Test Case Properties
JSON Values Description JSON Type
tcId Test case identifier integer
plainText An individual plainText HEX
ciphertext An individual ciphertext hex

9. Test Vector Responses

After the ACVP client downloads and processes a vector set, it must send the response vectors back to the ACVP server. The following table describes the JSON object that represents a vector set response.

Table 30: Response JSON Object
JSON Property Description JSON Type
acvVersion The version of the protocol string
vsId The vector set identifier integer
testGroups The test group data, see Table 31 array

An example of this is the following

{
        "acvVersion": "version",
        "vsId": 1,
        "testGroups": [ ... ]
}

The testGroups section is used to organize the ACVP client response in a similar manner to how it receives vectors. Several algorithms SHALL require the client to send back group level properties in their response. This structure helps accommodate that. The following is a skeleton for the test group structure. Additional properties may be included at this level depending on the algorithm, mode and revision.

Table 31: Response Test Group JSON Objects
JSON Property Description JSON Type
tgId The test group identifier integer
tests The test case data, depending on the algorithm see Table 32, Table 34, Table 36, Table 37, Table 38, Table 39 or Table 40 array

An example of this is the following

{
        "tgId": 1,
        "tests": [ ... ]
}

9.1. RSA keyGen Test Group Responses

Each test group contains an array of one or more test cases. Each test case is a JSON object that represents a single test vector to be processed by the ACVP client. The following table describes the JSON elements for each RSA / keyGen / * test vector.

The following table describes the JSON elements for the response to a RSA / keyGen / * test vector.

Table 32: RSA Test Case Results JSON Object
JSON Value Description JSON type
tcId Numeric identifier for the test case, unique across the entire vector set integer
e the public exponent hex
testPassed the verdict on the prime generation testing for the supplied pRand/qRand combination, see [FIPS186-4], Appendix B.3.3. boolean
seed the seed used in prime generation according to [FIPS186-4], Appendix B.3.2, B.3.4, or B.3.5 hex
bitlens the length of p1, p2, q1, and q2 for prime generation according to [FIPS186-4], Appendix B.3.2, B.3.4, B.3.5 or the length of xP1, xP2, xQ1, and xQ2 for B.3.6 array of integers
xP1 xP1 from [FIPS186-4] B.3.6, step 4, if applicable hex
xP2 xP2 from [FIPS186-4] B.3.6, step 4, if applicable hex
xP the random number used in Step 3 of the algorithm in [FIPS186-4], Appendix C.9 to generate the prime P, if applicable hex
p the private prime factor p hex
xQ1 xQ1 from [FIPS186-4] B.3.6, step 5, if applicable hex
xQ2 xQ2 from [FIPS186-4] B.3.6, step 5, if applicable hex
xQ the random number used in Step 3 of the algorithm in [FIPS186-4], Appendix C.9 to generate the prime Q, if applicable hex
q the private prime factor q hex
n the modulus hex
d the private exponent d hex
dmp1 the private exponent d modulo (p - 1) used in a Chinese Remainder Theorem private key hex
dmq1 the private exponent d modulo (q - 1) used in a Chinese Remainder Theorem private key hex
iqmp the multiplicative inverse of q modulo p used in a Chinese Remainder Theorem private key hex

Use the following applicability grid to determine which properties should be present based on the 'randPQ' test group property. The 'randPQ' property values for RSA / keyGen / FIPS186-4 are based on the section numbers in Appendix B in [FIPS186-4]. For RSA / keyGen / FIPS186-5, the property values are based on the true names of the generation methods. The RSA / keyGen / FIPS186-5 names will be listed in the grid. This grid only applies to 'AFT' test types.

Table 33: RSA Test Case Applicability Grid For AFT Responses
JSON Value Provable Probable Provable Primes With Conditions Provable Primes With Probable Conditions Probable Primes With Conditions
p yes yes yes yes yes
q yes yes yes yes yes
e yes yes yes yes yes
n yes yes yes yes yes
d yes yes yes yes yes
seed yes no yes yes no
xP no no no yes yes
xP1 no no no no yes
xP2 no no no no yes
xQ no no no yes yes
xQ1 no no no no yes
xQ2 no no no no yes
bitlens no no yes yes yes

The following is an example of an RSA / keyGen / * response. Test group 1 uses the provable prime (B.3.2) generation method. Test group 2 uses the provable prime with conditions (B.3.4) generation method. Test group 3 uses the provable prime with probable conditions (B.3.5) generation method. Test group 4 uses the probable prime with conditions (B.3.6) generation method. Test group 5 is for the 'KAT' test type for probable prime (B.3.3) generation method. Test group 6 uses the probable prime (B.3.3) generation method. In this example, 'infoGeneratedByServer' is set to true.
