Improved Cache Trace Attack on AES and CLEFIA by Considering Cache Miss and S-box Misalignment
Xin-jie ZHAO, Tao WANG
This paper presents an improved Cache trace attack on AES and CLEFIA by considering Cache miss trace information and S-box misalignment. In 2006, O. AcıiƧmez et al. present a trace driven Cache attack on AES first two rounds, and point out that if the Cache element number of the Cache block is 16, at most 48-bit of AES key can be obtained in the first round attack. Their attack is based on the ideal case when S-box elements are perfected aligned in the Cache block. However, this paper...
