Image encryption based on 2DNA encoding and chaotic 2D logistic map

Abstract DNA has recently been investigated as a possible medium concerning ultra-compact information storage and ultra-scale computation. The development of secure image encryption systems received certain effective new direction from chaos-based cryptographic algorithms. This paper proposes novel algorithm, 2DNALM , based on double-dynamic sequence chaotic 2D logistic map. three phases regarding the suggested approach are follows: first phase involves permuting positions pixels using position key-based scrambling operation. second double encoding scrambled images various rules by cryptography concept to produce an encoded image, in final step, which is encrypted XOR operation keys created through entropy analysis experimental findings show that scheme exhibits great withstands several common attacks.
