Abstract

COQCRYPTOLINE is an automatic certified verification tool for cryptographic programs. It is built on OCAML programs extracted from algorithms fully certified in COQ with SS- REFLECT. Similar to other automatic tools, COQCRYPTO- LINE calls external decision procedures during verification. To ensure correctness, all answers from external decision procedures are validated by certified certificate checkers in COQCRYPTOLINE. We evaluate COQCRYPTOLINE on cryp- tographic programs from BITCOIN, BORINGSSL, NSS, and OPENSSL. The first certified verification of the reference implementation for number theoretic transform in the post- quantum key exchange mechanism KYBER is also reported.
