摘 要: 混沌序列具有带宽大、类噪声、难于预测和重构等特点,因而非常适用于网络通信和数据加密。本文结合神经网络和混沌映射的特点,提出了一种基于混沌神经网络和混沌映射序列密码的设计方法,该方法可以克服有限精度效应对混沌系统的影响,从而改善混沌序列特性,理论和实验结果表明:在有限精度实现下,该方法可以有效提高混沌系统的复杂性和随机性,并且算法安全性高、运算速度快,并且便于软硬件的实现。 As we all know, chaotic system is sensitive to initial values and system parameters, so it is suitable for information encryption. In this paper, a stream cryptographic algorithm based on chaotic neural network is proposed, this scheme can improve the complexity and the period of the chaotic system under the finite-precision circumstances. The theoretic and simulation show that the new approach not only owns high complexity, good randomness properties , but also has high security and implemented easily in both software and hardware.
