摘要
介绍了DES加密算法和混沌加密算法,在结合两者优良特性的基础上,提出了一种基于Lorenz系统和DES加密算法的混合加密方案,该算法利用Lorenz混沌方程生成DES所需要的密钥,大大扩展了DES加密算法的密钥空间,同时通过C++程序实现了该加密算法,实验结果表明该算法具有可行性。
The DES encryption algorithm and the characteristics of chaotic encryption algorithm were introduced and one kind of hybrid encryption algorithm based on Lorenz chaos equations and DES was also proposed, based on super advantages of two methods concerned. The algorithm generate DES cryptographic key by Lorenz chaos equations, greatly expanding the DES encryption algorithm cryptographic key space. Simultaneously, C＋＋ procedure was used to realize this algorithm, the experimental results show that the algorithm is feasible.
