| 摘 要： | 提出了一个对称分组密码算法——PEA K。其分组长度为128bit,密钥长度为128bit到512bit可变,但要64bit对齐。该算法整体结构为变种的非平衡Feistel网络,具有天然的加解密相似性。同时在设计中采用了宽轨迹策略,确保算法对差分密码分析和线性密码分析的安全性。该文的目的是寻求公众对PEAK分组密码的测试、分析和评估。

| Abstract: | A new symmetric block ciphering algorithm PEAK is presented in this paper.It is the 128-bit block cipher and can accept keys from 128 bits to 512 bits,aligned to 64 bits.The whole structure of the cipher is a non-balance Feistel variation network whose decryption on-ly differs from the encryption in the key schedule.With the wide trail strategy used,the cryp-tographic security against the differential and linear cryptanalysis is ensured.The goal of this paper is the publication of the PEAK block cipher for public scrutiny. |
