摘　　要：混沌序列具有对初始条件的敏感性和伪随机性,可用作高安全性的序列密码。文中提出了基于Lorenz混沌系统和四阶细胞神经网络(CNN)超混沌系统的数字签名方法,实现了对中文文档的数字签名。仿真结果表明,其具有很强的抗攻击性,而且计算量小,处理数据速度快,密钥取值范围广,具有广泛的应用前景。The chaotic sequence is pseudo-random and sensitive on initial value. It can be used as secure sequence cipher. In this paper, a kind of digital signature is presented, which is based on the Lorenz chaotic system and the four step cell neuron net （CNN） hyperchaotic system. The digital signature of Chinese document is realized. The simulation indicates that it has advantages such as small quantity of calculation, fast encryption and large extensive key＇s choice.
