【摘要】 本文推出了一个分组长度和密钥长度均为128bit的分组密码—AC(a cipher),它的整体结构是SP网络,加解密是相似的。AC分组密码的设计结合了宽轨迹策略和比特块技术,以确保算法对差分密码分析和线性密码分析的安全性。本文的目的是寻求公众对AC分组密码的测试、分析和评估。更多还原

【Abstract】 AC(a cipher) is a 128-bit block cipher that accepts a 128-bit key. The cipher is a substitution-permutation network whose decryption only differs from the encryption in the key schedule. The cipher design combines the wide trail strategy and bit-slice technology that ensure the resistance AC against differential and linear cryptanalysis. The goal of this paper is the publication of the AC block cipher for public scrutiny.更多还原
