一种基于四维混沌神经网络的通信数据加密算法

混沌神经网络序列具有带宽大、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.本文提出一种四维混沌神经网络序列的产生方法,利用四维混沌神经网络进行混合加密,所产生的二值序列对明文进行预处理.实验结果表明,该系统对产生的二值序列,具有良好的初值敏感度,序列随机性较为理想,同时,四维混沌神经网络大大增加了密钥空间,利...

Novel approach for generating binary chaotic sequences and its application to data encryption based on 4-D chaostic neural network

Chaotic neural network series is very suitable for network communication and data encryption with the merits that it is broad bandwidth,unpredictable and reconfigurable.In this paper,a stream cryptographic algorithm based on 4-D chaostic neural network is proposed,which preprocesses the plaintext using the binary sequences.The experimental results show that the system to produce binary sequences,with good initial value sensitivity,sequence randomness ideal,and at the same time,4-dimensional chaotic cellular...
