密码结构 meaning in Chinese
combination mechanism
cryptography architecture
Examples
- So we do n ' t recommend this kind of cipher structure when designing a new cipher . 5
因此在分组密码的设计中，我们不推荐使用这类密码结构。 - 4 . security of a class of block ciphers based on chaotic maps against differential and linear cryptanalysis is studied . the results show that this kind of cipher structure is not good compared with some famous cipher structure such as cast - 256 cipher structure and common feistel structure
对一类基于混沌函数的分组密码结构gfs4 ( gfs8 )的安全性做了评估，分析结果表明：从抵抗差分密码分析和线性密码分析的安全性与所需要的执行代价相比，这类密码结构不如cast - 256型密码结构和普通的feistel型密码结构。 - The structures , styles , advantages and disadvantages of some frequently used block ciphers are given in detail . the design rules and the structure methods for the round - function , s - boxes , p - permutation of the block cipher as well as several rules for the key - expansion algorithm are discussed in detail . the most two typical block ciphers , rijindael algorithm ( advanced encryption standard ) and camellia algorithm ( new european schemes for signatures , integrity and encryption ) are introduced
本论文首先介绍了国内外现有的几种攻击分组密码的典型方法，包括差分密码分析、线性密码分析以及针对aes的代数攻击的最新进展；然后针对各种已有的密码攻击手段，给出了分组密码的一般设计原理，并详细阐述了分组密码结构类型及其各个部件的设计准则和构造方法，最后介绍了当前国际上最具有代表性的两个分组密码算法? rijndael算法(高级加密标准)和camellia算法(新的欧洲签名、完整性认证和加密方案) 。
