Cryptographic Protocol Review overview

Security-focused review workflow for evaluating the correctness, security properties, and implementation soundness of cryptographic protocols and primitives before they are deployed in production. The security engineer documents the threat model, security goals, and cryptographic assumptions for the protocol. The architect reviews the design against known attack classes — chosen-plaintext, replay, downgrade, and side-channel attacks. A formal or semi-formal analysis of the protocol's security properties is conducted, and the implementation is audited for constant-time operations, safe randomness, and correct parameter selection.
