Title:
An Improved Trace Driven Instruction Cache Timing Attack on RSA
Authors: Chen Cai-Sen, Wang Tao, Chen Xiao-Cen, Zhou Ping
Abstract:The previous I-cache timing attacks on RSA which exploit the instruction path of a cipher were mostly proof-of-concept, and it is harder to put them into practice than D-cache timing attacks. We propose a new trace driven timing attack model based on spying on the whole I-cache. An improved analysis algorithm of the exponent using the characteristic of the size of the window is advanced, which could further reduce the search space of the bits of the key than the former and provide an error detection mechanism to detect some erroneous decisions of the operation sequence. We implemented an attack on RSA of OpenSSL under a practical environment, proving that the feasibility and effectiveness of I-Cache timing attack could be improved.
