Title: "From Silicon to C: Reverse-Engineering Cryptographic Hardware"

Abstract:
This talk looks at the possibility of reverse-engineering proprietary algorithms from hardware. I present a mostly automated approach to reconstructing functionality by using a combination of image analysis of circuits and protocol analysis. The cryptography my approach finds on a widely deployed "secure" RFID token has several vulnerabilities including weaknesses in the random number generator and very low resistance against brute-force attacks. I will further raise the question of how small cryptography can be implemented and present our design for a small hash function that reuses circuitry already found on RFID tags.
