CAVP Testing: SP 800-108 Key Derivation Using Pseudorandom Functions - Key-Based (KBKDF)

Algorithm Specifications

Algorithm specifications for Key-Based KDFs (SP800-108) are available from the Cryptographic Toolkit.

Algorithm Validation Testing Requirements

The algorithm validation testing requirements for SP 800-108 are specified in: The SP800-108 Key Derivation Function Validation System (KBKDFVS).

Testing Notes

• Prerequisites for KBKDF testing are listed in the CAVP Frequently Asked Questions (CAVP FAQ) General Question GEN.5.

• As of 1-1-2016, TDES KO2 encrypt is no longer compliant. (See SP800-131A Revision 1.)

Test Vectors

Use of these test vectors does not replace validation obtained through the CAVP.

The test vectors linked below can be used to informally verify the correctness of the KBKDF algorithm listed above.

See the KBKDFVS document for an explanation of the files.
