The quantum computing revolution isn’t coming; it’s already knocking at our door. Shor’s algorithm threatens to dismantle RSA and ECC encryption in mere hours once cryptographically relevant quantum computers (CRQCs) arrive, while Grover’s algorithm halves the security of symmetric encryption. For industries with long lifecycle products including automotive, aerospace, defense, and critical infrastructure – this isn’t a distant concern. It is almost guaranteed that a vehicle or satellite launched today with fixed-function cryptographic hardware will be operational well past “Q-Day,” the moment quantum supremacy renders classical encryption obsolete. The stakes couldn’t be higher: without agility, we’re not just risking data breaches, we’re guaranteeing them.
