摘要
基于高维混沌并通过一些关键技术产生的序列具有均匀分布、好的相关性和长周期的特点。利用这些序列建立了三重DES模型,较好的解决了三重DES初始密钥的保存和传输问题,使系统具有更好的安全性。为了增强安全性,进一步提出了动态密钥3DES算法,使系统有很强的抗破译能力。
The sequence based on Multi-dimension chaos by some key techniques has uniform distribution, long period and good correlation. 3DES model is established through the sequence, and resolve good the problem that the 3DES′ key is saved and is transmitted,and make the model has good security. Dynamic key 3DES algorithm is proposed, which has higher security, great non-crack ability and wide applicability .
