摘要:
结合反馈型离散Hopfield神经网络(HNN)和改进型的线性反馈移位寄存器(M-LFSR)的优点,提出基于OHNN和M-LFSR的字序列密码.该方案利用离散Hopfield神经网络的混沌吸引子对改进型线性反馈移位寄存器的非线性选择输出,实现加密.安全性分析与仿真验证表明:该算法构造的伪随机序列具有良好的随机性、复杂度等特点,满足密码学的要求.
Abstract:
A new encryption technique in word-oriented stream cipher has been proposed. It consists modified linear feedback shift register simu-lated(M-LFSR), and a feedback discrete-time Hopfield neural networks(HNN). Nonlinearity of the M-LFSR has been chosen by the chaotic attractors of discrete-time HNN as the output to achieve encryption. Safety analysis and simulation have shown that the pseudo-random sequence constructed by the proposed algorithm has been characterized by good randomness and complexity, which meets the requirements of cryptography.
