Approach to Post Quantum Cryptography Validation

This paper outlines the procedure for validating cryptographic modules that implement Post Quantum Cryptography (PQC) algorithms. It highlights public key encryption schemes, particularly PKE as well as the Module Lattice based Key Encapsulation Mechanism (KEM) for CRYSTALS Kyber, both of which are included in the proposed standard NIST FIPS 203. The validation process entails submitting test vectors to the Implementation Under Test (IUT), aligning with NIST's validation methods, akin to those used for various FIPS approved algorithms like AES and SHA3. These PQC algorithms can be implemented by the vendors across various platforms, including hardware, software, and firmware. The test vectors generated act as basis for the Cryptographic Module Validation Testing (CMVT) to authenticate encryption components that incorporate these PQC algorithms.
