Hyperchaos based search cheat image encryption algorithm
Yong Zhang · 2010
A novel search cheat image encryption algorithm based on hyper-chaotic Chen-system is proposed. Through mapping plain image and cheat image into hyper-chaos variables, the search and iteration algorithm is employed to encrypt plaint image to cheat image that is transferred to receiver in network. Security and performance analysis shows that this method can cheat attackers and has the same confidentiality as cover encryption.
