This section focuses on classical cryptography built to resist quantum attack — the lattice, hash, code, isogeny, and multivariate families — together with their standardization and deployment.
Use the sequence below as the local map for this section. Post-quantum cryptography is classical mathematics on classical hardware; it is distinct from the quantum-native protocols in Quantum Key Distribution, shares its foundation with Homomorphic Encryption, and rests on Lattices.
