基于OCML彩色图像加密算法的分析和改进
首发时间:2010-01-08
摘要:在本文中,我们对基于OCML彩色图像的加密算法进行了介绍,通过对其安全性的分析,从密钥的产生和加密过程提出了改进。使用128bit的密钥来产生初始条件和系统参数,代入混沌映射来加密图像,并完成了解密的工作。进行了统计性分析,相关性分析以及信息熵分析,测试得到的结果满足预期目标。

The analysis and improvement of OCML-based color image encryption
Abstract:In this paper, OCML-based color image encryption was introduced. With the help of the analysis of its security, we have improved the key generation and encryption process. We use 128bit key to generate the initial conditions and system parameters. Substituted into the chaotic maps to encrypt images, and completed the decryption work. We have finished the analysis of statistical, related and information entropy. The results obtained to meet the target.
Keywords: chaos image encryption OCML
