| Abstract: | In this paper,an image encryption system on computer is designed and simulated by programming.Also a hybrid coding scheme for still digital images is proposed. Image compression data is whitened by m sequence, and the initial status of encryption and primitive polynomial of m sequence are accomplished by using RSA poublic key cryptosystem. |
