Kun Zhang, Xing-an Fu · 2012
Chaotic encryption has presently become the focus of the information security field. The article presents the main theory of TD-ERCS, and proposes a new algorithm to improve the security of image encryption based on TD-ERCS. According to the sort permutation and the binary XOR operation from the TD-ERCS chaotic series, it can achieve image encryption. This encryption algorithm is a reversible algorithm, and it can achieve the original image in the rule inverse process of the encryption algorithm. Finally, through computer simulation, the experiment results show that the new chaotic encryption algorithm based on TD-ERCS is valid and has higher security.
