摘要
随着多媒体技术和网络技术的发展,数字图像信息安全问题引起了人们的广泛关注。通过分析目前混沌理论在数字加密中的应用的现状,利用陈氏超混沌系统和广义猫映射对数字图像进行了加密研究。Matlab仿真实验证明,加密效果良好。
With the development of multimedia technology and the development of computer network,the digital image information security problems caused by more and more people＇s attention.This article,through the analysis of chaos theory in digital encryption application status,use Chen hyperchaotic system and generalized cat map for digital image encryption research.The Matlab simulation results show that the experimental proof,good encryption effect.
