摘要
文章致力于对现有的数据加密算法的安全性进行密码学分析,并在此基础上设计了一种基于混沌系统的加密算法。文章设计的混沌加密算法是一种基于离散混沌系统模型中的Logistic映射的序列密码算法,通过对混沌公式的迭代得出密钥,将密钥与明文中的每个字节进行异或,得出密文,从而实现对数据的加密。
This paper is committed to the existing data encryption algorithm for the security of cryptographic analysis, and on the basis of this design of a chaotic system based on the encryption algorithm. In this paper, the design of the chaotic encryption algorithm is a model based on discrete chaotic system in the mapping of the sequence Logistic dipher algorithm, through the chaos of the iterative formula derived key, will be key and express to each byte XOR, the ciphertext is gotton in order to realize the data encryption.
