An Improved Compound Image Encryption Scheme

摘要：

With the development of network technique, the research of information security technique is becoming more and more important. In this paper, we propose an improved image encryption scheme. The image is encrypted through the combination of a new gray value substitution operation and position permutation which makes the encryption system strong. Experimental results show that the scheme proposed in this paper can resist the attack of selective plaintext and has a high security level.
