Definition
The term, in context
AI-assisted draft · approved dataset
HQC is a code-based key encapsulation mechanism built on quasi-cyclic codes, deriving its security from the hardness of decoding a random quasi-cyclic linear code rather than from structured lattices. Assigned the FIPS 207 designation, it serves as an algorithmically independent alternative to lattice-based encapsulation, so a break in lattice assumptions would not compromise both at once.

As of 2026-10-01, verified readiness is 20 (claimed 35, reported 35, gap 15) — Strong evidence strength; current signals suggest Evaluate HQC in version-pinned experimental integrations.
The readiness fact belongs to the canonical Readiness Verdict for HQC (FIPS 207).
