Securing the IoT: High-speed cryptography and Edward Snowden
summary
Work on car-to-car security yields a $10 prototype crypto engine that performs 1500 signatures/sec, meeting latency and cost targets for V2V authentication and supporting field trials; it targets elliptic-curve signing of ~100-byte heartbeat messages at 10 Hz. Research also demonstrates a dopant-level Trojan that collapses a TRNG from ~2^256 possibilities to a 2^32 keyspace, making offline key recovery trivial; the modification is hard to spot in layout but can be detected with targeted SEM-based inspection, motivating supply-chain and testing changes.
