Secure AI with Quantum‑Proof Zero Trust

A new idea keeps artificial intelligence safe even when quantum computers arrive. It blends two modern security tools: post‑quantum cryptography, which stays strong against quantum attacks, and zero trust architecture, where no device or user is automatically trusted. The designers use a branch of mathematics called category theory to describe how the system works. They think of cryptographic steps as arrows and trust rules as maps that connect those arrows, making the whole chain easier to prove correct.Because of this design, the system can break an AI network into tiny isolated zones and change trust levels on the fly. That makes it harder for attackers to tamper with models or data. The theory was tested on a small microcontroller board. After adding the new security, the device used almost all of its memory for cryptography but still ran fast. Every attempt to access the AI model without permission was stopped instantly, and the delay added was less than a millisecond. This experiment shows that it is possible to build practical, quantum‑ready AI security with solid mathematical backing.
