Image Cheat Encryption Algorithm Based on Hyperchaotic System
Yong Zhang · 2010
In this paper, a novel image cheat-encryption algori-thm based on hyper-chaotic Chen-system is proposed. The hyper-chaos is employed to encrypt plain image into cheat-like image. The cheat-image is transferred in network and easily neglected by attackers. If cheat succeeds, it is impossible to decrypt. When the cheat-image fails to cheat the attackers, security and performance analysis shows the cheat-encryption method still has the same confidentiality as the cover-encryption.
