Zero Trust Meets Post-Quantum Cryptography: Shipping Kyber in Modern Microservice Communication
As quantum computers advance, Shor's algorithm will break today's RSA and ECC public-key systems in polynomial time, and the Harvest Now, Decrypt Later threat is already here. This article takes apart the Kyber key encapsulation mechanism built on the Module-LWE lattice problem, then walks through a seamless upgrade to a hybrid post-quantum TLS 1.3 handshake on a production microservice gateway.
