混沌序列在信息保密中的应用研究

混沌序列由形式简单的非线性方程产生,具有初始条件敏感性、非周期性、类随机性和较宽的频谱等优良的密码学性能,混沌序列应用信息保密,进行加密已成为现代密码学研究的新方向.分析了该研究的最新进展,指出目前建立混沌时间序列加密算法中的几个技术问题,提出了改进方案,并对今后技术发展方向提出了建设意见.

Study on the application of chaotic encryption

Chaotic time series came from chaotic system is of cryptographical properties, such as the sensitivity to the initial condition, non-periodic, pseudo-random and periodicity, appling it to encrypt has becoming new thesis. The development of the domain is briefly reviewed. The authors point out some existent problems in digital chaotic ciphers and give a new solution,forecasts the further studies.
