Combining DNA cryptography with chaotic system,we present a color image encryption algorithm based on DNA sequence.This algorithm applies addition,subtraction and xor operations to DNA sequence,and decomposes a color image into bit-planes.We firstly decompose a color image into bit-planes and encode the them by DNA sequence.Likewise,we perform scrambling,addition and xor operations on every DNA-plane.Then,we decode the DNA-planse and compose the bit-planes into an encrypted image.Experimental results show that the encrypted image is noise-like,highly sensitive to the keys,has a flat histogram,good randomness and low correlation between two adjacent pixels.
