| Abstract: | It puts forward an image scrambling algorithm based on the Rijndael, solved the problem of M×N multicolor image encryption. The algorithm had the characteristics of being sensitive to the key, having large key space, and having good image pixel dispersivity after encryption. It ensured the security of the encrypted image. Using the method of object oriented analysis and designing, it designed an image scrambling algorithm system. This system solved the problem of gray image encryption and multicolor image encryption. |
