| 摘 要： | 混沌系统对初始值的极端敏感,使得它呈现出类随机性和数据难以预测的特点,因此在安全通信和算法加密设计方面得到了许多应用.数字签名技术是网络信息传输过程中经常应用的加密技术,不同于多数系统中经常采用的非对称加密技术,提出了一种基于超混沌强化对称加密算法的数字签名技术,通过对DES算法的入口参数进行混沌加密,而使得对称算法得到了进一步的增强,给出了数字签名算法的实现过程并给出了该方法在局域网信息安全传输中的应用.

| Abstract: | The chaotic system is sensitive to initial values that makes it has some characters such as randomization and unpredictability, so chaos is widely used in secure communication and encryption. A new digital signature method that is different from asymmetric encrypt algorithms often used in most digital signature systems, is proposed based on encrypt arithmetic of symmetry enforced by hyper-chaos, the symmetric encrypt algorithms is enforced by encrypting entry parameters of the DES arithmetic. The process of digital signature is presented and application of the proposed method in transmission of information based on network is stated explicitly. |
