An Novel Chaotic Image Encryption Algorithm based on Tangent-Delay Ellipse Reflecting Cavity Map System

In order to effectively protect digital image information, to improve the efficiency and security of the encrypted image, many effective and feasible image encryption algorithms have been proposed. The recovery is depended on the recovery value of pixel 8 bits plane; the incorrect from low to high pixel value of plane affect the incorrect of Index of all proportion to the pixel value, resulting in the restoration of image quality. Based on the study of digital image encryption technology, the essay proposes the image encryption algorithm based on TD-RECS chaotic system, and the decryption algorithm against attack on the basis of it.
