We present Copker, the first work that exploits on-chip cache to implement the RSA cryptosystem entirely within CPU. Copker protects private keys from attackers who have physical access to the machine (e.g., cold-boot attacks). The large size of cache allows memory-intensive algorithms, such as CRT-enabled RSA, to be implemented without RAM.
