Definition
The term, in context
AI-assisted draft · approved dataset
NIST HQC is a code-based key encapsulation mechanism selected as a backup to the primary lattice-based post-quantum standard, so that public-key encryption does not rest on a single family of mathematical assumptions. Its security derives from the difficulty of decoding random quasi-cyclic codes, an unrelated hard problem, meaning a future break in lattice assumptions would not automatically carry over to it.
