摘　　要：研究了多媒体图像加密解密的相关技术,对相关的加密算法进行了研讨和实现,主要对三种图像置乱算法利用MATLAB软件进行了编程实现。首先对像素置乱、行列置乱、色彩饱和度置乱三种算法进行实现,分析不同算法的加密效果。然后用三种加密方法对选取的同一图片进行了加密解密实现,比较加密效果,分析三种算法各自的优缺点。The encryption and decryption technology of multimedia image is focused on. The relevant encryption algorithms are in the discussion and implementation. Three image scrambling algorithm are applied and carried out using MATLAB programming. The three algorithms of pixel scrambling, row scrambling and color saturation scrambling are analyzed, and have a general understanding of the encryption effect of different algorithms. Then use three encryption method to select the same image to achieve encryption and decryption. Finally, give a comparative analysis of the three methods＇ effect of encryption and decryption, advantages and disadvantages of the three algorithms are summarized.
