Enabling Crypto Agility by Immunizing Processors Against the Exploitation of Software Bugs

summary
Moving cryptography back into software buys crypto agility but exposes keys and algorithms to software bugs, side channels and update-supply-chain attacks. Hardware options include a separate secure core (higher area and cost) or virtualization (API attack surface); ML profiling gives false positives and negatives. A concrete alternative is metadata tracking on instructions and data to enforce control-flow integrity, full memory safety and data privacy, pinpoint exploit PCs, and report vectors for targeted secure updates. Gartner predicts RSA‑2048 fragility around 2025–2030.
