Authenticate everything
summary
Claims that commodity SRAM power-up fingerprints yield stable device keys and demonstrate a working pipeline: read SRAM power-up fingerprint at manufacturing, run a fuzzy extractor + error‑correction to produce a stable cryptographic key, and perform one-time provisioning so no secret is written to flash. Shows this works on standard chips (no special silicon), scales to billions of devices, and prevents key exfiltration by removing persistent key storage.
