# The Quantum Transition Meets a New Risk, Namely AI-Assisted Cryptography Code

A research paper warns that large language models introduce subtle, dangerous errors into post-quantum cryptography, where constant-time execution and side-channel resistance leave no room for mistakes.

As major chains and custodians move quantum resistance from theory into their development plans, a new paper highlights a risk in how that code is written. The study examines secure-coding drift in AI-assisted post-quantum cryptography deve…
