A NOISE-RESISTIVE PICTURE ENCRYPTION BY APPLYING DNA SEQUENCE OPERATION

  • Mathiyalagan R

Abstract

Using the combination of chaos, hyper-chaos, and DNA sequence operation, this paper proposes an image encryption method. Three phases of encryption operations are carried out by the suggested method. Such are selection-level hyper-chaotic DNA-shuffling operation based on sequence, key-image-based DNA-diffusion operation, and DNA-shuffling operation based on hyper-chaotic sequence. The benefits of this scheme are higher key space, higher uncertainty or randomness of pixels, higher sensitivity to the keys and plaintext pixels, greater resistivity to the noises, and lossless encryption and decryption. In addition, the selection-level hyper-chaotic DNA-shuffling operation based on sequence produces more complexities in the process of uncertainty that increases the strength of encryptions and decryptions. The computer simulation and security tests confirm the good results of the proposed system's encryption results and high resistivity to the attacks commonly used
