Bo Liu, Liu Na, Jianxia Li, Liang Wei · 2011
This paper introduces a method of image encryption algorithm which was improved. Chaotic sequence is generated by the Logistic chaos mapping. Image encryption is realized by gray value of substitutes and pixel position scrambling. Encryption algorithm and decryption algorithm use Matlab to simulate image. The results proved the feasibility of the proposed algorithm.
