| 摘 要： | 鉴于传统图像加密技术和低维混沌加密技术各有其局限性,该文中提出了一种利用Lorenz系统产生混沌序列,并结合混沌镜像加密方法的三维超混沌图像加密方法。该方案对初始密钥敏感强,对混沌序列的预处理时间短,是一种具有较高的安全性,加密效率高,且易于实现的图像加密算法。

| Abstract: | In view of the fact that the traditional image encryption technology and the low dimension chaos encryption technology respectively had its limitation,in this paper we discussed a new image encryption algorithm based-on the Lorenz system using chaotic mirror-like image encryption algorithm.For its sensitive dependence on the initial condition and the generation of chaos sequence in short time,the algorithm provides good security,the high encryption efficiency.Experimental results are satisfactory. |
