Combining DNA cryptography with chaotic system, a color image encryption algorithm based on DNA sequence is presented.This algorithm applies the addition, subtraction and xor operation for DNA sequence,and decomposes color image into bit-plane.First of all,we decompose color image into bit-plane and encode bit-plane by DNA sequence.Otherwise,we process every DNA-plane by scrambling,addition and xor operation for DNA sequence.In the end, we decode DNA-plane and composes bit-plane into encrypted image.Experimental results show that the image ...
