Post-Quantum Cryptography on Embedded Systems: Memory, Latency and Upgrade Paths
The chip in your car, your hospital’s infusion pump, your building’s security panel — may not be upgradeable. For much of the deployed hardware, the path ends in physical replacement. Here’s the board-level reality nobody’s published yet.
