How do cybersecurity experts discover how to properly defend a system or build a network that's secure?As in other domains of science, this process involves hypothesis, experimentation, and analysis -...
Performance Evaluation of Safer K-64 and S-Boxes of the Safer Family
Performance Evaluation Safer K-64 S-Boxes Safer Family
2009/7/27
If the characteristics of s-boxes of the SAFER family of ciphers are examined for the criteria of strict avalanche, bit independence, and XOR table distribution, experiments show that the ``exponentia...
SAFER-64的多重线性密码分析
多重线性密码分析 线性逼近 SAFER-64
2008/4/27
研究了SAFER-64基础模块的密码特性和建立六轮加密的线性逼近式及其优势，从理论上证明了本文的线性逼近式的优势只与第2、3、6、7字节的种子密钥有关，与其他子密钥无关，从而可以运用多重线性密码分析法攻击第2、3、6、7字节密钥.
通过对SARER-64系统基础模块的深入分析，构建了由6个线性逼近式组成的循环逼近式系统.由于循环性，该逼近式系统可以用来对任意轮次的SARER-64进行多重线性密码分析，从而确定系统的弱密钥.现以五轮SARER-64为例，构建多重线性逼近式并分析系统的弱密钥.
