A Survey on Cache Timing Channel Attacks for Multicore Processors

Cache timing channel attacks has attained a lot of attention in the last decade. These exploits created by significant time gap between cache and main memory accesses. It been successfully implemented to leak secret key various cryptography algorithms. The latest advancements also exploit other micro-architectural components such as hardware prefetchers, branch predictor, replacement engine, addition memory. Detection these is difficult task attacker process running processor must be detected before portion attack complete. major challenge for mitigation defense mechanisms against maintaining system performance while disabling or avoiding attacks. overhead caused detection, mechanism not system’s performance. This paper discusses research carried out three aspects security: attacks, detection techniques details.
