基于公共协方差矩阵的实用模板攻击
Practical template attacks based on pooled covariance matrix
摘要
Abstract
Aiming at the problem of training sample amount to template attack of block cipher,this paper proposed the expres-sion of the sample amount by probability analyzing.Meanwhile,aiming at the limited number of training samples,this paper presented a template attack method based on pooled covariance matrix.Experimental results from attacking 10000 AES encryp-tion traces show that the proposed method not only can avoid the numerical problems,but also its success rate is significantly better than the traditional template attacks.关键词
