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 .
