PQC concepts
What is Code-based cryptography?
Cryptography whose security reduces to decoding random linear codes. McEliece (1978), HQC, BIKE, CROSS. Longest cryptanalytic track record of any PQC family.
Decision context
Why Code-based cryptography matters
Code-based cryptography provides mathematical diversity from lattice and hash-based designs. Schemes in this family vary widely in key size, decoder design, performance, maturity and standardization status, so the family name alone is not a deployable security profile.
How to evaluate Code-based cryptography
Evaluate the exact code problem, parameter set, decoder, object sizes and implementation revision. Exercise known-answer and invalid-input tests and measure the real protocol path. Separate long cryptanalytic history from proof that a particular implementation or integration is production-ready.
PQC concepts
PQC concepts evidence boundary
Post-quantum programmes combine cryptography, architecture, data lifetime, operational ownership, and migration governance. A concept is useful only when it changes a concrete inventory, policy, design, test, or evidence decision. Treat terminology as a decision aid rather than proof that a control exists.
