摘要
提出一种基于一维可逆元胞自动机(RCA)的新的图像加密算法,算法中可逆元胞自动机(RCA)规则和随机数据的应用使得图像具有更高安全性。可逆元胞自动机(RCA)加密算法将已知灰度图像变为二值图像.然后将其数据重新排列成一0-1序列,应用可逆元胞自动机(RCA)规则实现图像加密。灰度图像加密的仿真结果表明所提出的算法满足混合特性和扩散特性,一般的解密算法根本不可能对这种加密图像解密。
A new approach to image encryption was proposed based on one dimensional reversible cellular automata （RCA）. The encryption method can encrypt images with higher security because RCA rules and randomness of the data were used in the process of encryption. When using RCA to encrypt, such application converted the given gray level image into binary image and rearranges the data as a sequence of 0-1 data. The use of RCA＇ s principles implemented image encryption. Simulation results for gray level images expatiated that the proposed encryption method satisfied the properties of confusion and diffusion. However, more perfect guess of encryption key made decryption impossible, this encryption method worked well as it＇s expectated.
