摘要
在信息安全技术中,分组密码算法的研究一直是人们关注的热点,本文简单介绍了两种具有代表性的分组密码算法:基于Feistel结构的DES算法和基于SP结构的AES算法,并在分析两种算法的原理的基础上分析了Feistel结构和SP结构的特点。
In the information of safe technology, the research of grouping cipher algorithm is always the hot pointthat people pay attention to, this paper simply introduces two representative grouping cipher algorithm: the DESalgorithm based on Feistel structure and the AES algorithm based on SP structureUnder the analysis of twoalgorithm's principle, we get the characteristic of Feistel structural and SP structure.
