基于公共协方差矩阵的实用模板攻击OA北大核心CSCDCSTPCD
Practical template attacks based on pooled covariance matrix
针对分组密码算法模板攻击所需训练样本数量问题进行研究。通过概率分析,推导出所需样本数量的数学表达式,同时针对训练样本数量有限的情况,提出了一种基于公共协方差矩阵的实用模板攻击方法。通过对10000条 AES 样本曲线进行攻击,实验结果表明,该方法不仅可以避免产生数值问题,而且攻击成功率显著优于传统模板攻击方法。
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 …查看全部>>
