Building an AI-Resistant Post-Quantum VPN in Rust 🦀 (With an Open Crypto Challenge)

Hello Dev.to! 👋

I'm the architect of an experimental post-quantum VPN protocol called QCRA (Quantum-Chess Routing Architecture). It’s written entirely in Rust (250K+ lines, 46 passing test suites).

Today, I’m open-sourcing the protocol specification along with a Cryptographic Open Challenge for anyone who wants to try and break the math.

The standard approach to post-quantum networking today is to take ML-KEM (Kyber), wrap it in a TLS-like handshake, and call it a day. While this protects against Shor's algorithm on future quantum computers, it ignores an entirely different, very modern threat vector: AI-Driven Traffic Analysis.

Modern machine learning classifiers can identify encrypted VPN traffic with >99% accuracy. They don't need to decrypt your packets; they exploit statistical discontinuities, packet timing, and size patterns.
