This paper blends post-quantum cryptography (PQC) and zero trust
architecture (ZTA) to secure the access for AI models, formalized through
the abstract mathematical lens of category theory. In this work, latticebased
PQC primitives are assigned ZTA components that include microsegmentation
and context-aware authentication, leading to a visual compositional
framework that describes cryptographic workflows as morphisms
and trust policies as functors, showing how category theory allows for
fine-grained policies and adaptive trust. This quantum-resistant algorithm
viewing perspective offers an ease for protection against adversarial
AI threats. The paper uses a concrete implementation to attest to the
effectiveness of the theoretical contribution, rendering it a crypto-agile
transition using categorical proofs for AI security .
