Accelerating memory decryption and authentication with frequent value prediction
2007
Proceedings of the 4th international conference on Computing frontiers - CF '07
This paper presents a novel architectural technique to hide fetch latency overhead of hardware encrypted and authenticated memory. A number of recent secure processor designs have used memory block encryption and authentication to protect un-trusted external memory. However, the latency overhead of certain encryption modes or authentication schemes can be intolerably high. This paper proposes novel techniques called frequent value ciphertext speculation and frequent value MAC speculation that
