A family of cryptographic algorithms designed to remain secure against attacks from both classical computers and quantum computers. The defining parameters are: (1) resistance to Shor's algorithm and Grover's algorithm attacks, which threaten RSA, ECC, and symmetric schemes respectively; (2) reliance on mathematical problems believed to be hard even for quantum adversaries — lattice-based, code-based, hash-based, or multivariate polynomial problems; (3) specification through formal security reductions that bound the advantage of any quantum adversary in terms of worst-case hardness of underlying problems. The persistence mechanism is standardization (NIST PQC standardization process), implementation in cryptographic protocols and libraries, and continuous cryptanalytic scrutiny that prunes insecure candidates while validated schemes enter deployment.

Quantum-safe cryptography is entirely built on mathematical constructs — lattice problems, code-based hardness assumptions, multivariate equations. Its security proofs ARE mathematical theorems. Remove mathematics and quantum-safe cryptography ceases to exist as a discipline; there is no framework for defining or proving security. This is constitutive, not merely facilitative.

Direction tested: quantum-safe cryptography IS a specific kind of cryptography — it is cryptographic algorithms and protocols designed to operate securely against attacks by quantum computers. A competent speaker would call it a type of cryptography. Law 9: specific to general.

Quantum-safe cryptography emerged as a direct response to the threat that quantum computers pose to classical cryptography. Quantum computing existed first and fed into the creation of quantum-safe cryptographic methods. Per Law 7 DERIVED_FROM: which existed first? Quantum computing predates the specific field of quantum-safe cryptography.
