Color Image Encryption Algorithm Based on Julia Set and DNA Coding
Security is very important in the process of image transmission.In order to ensure the safe transmission of image in-formation,a color image encryption algorithm based on Julia set and DNA coding is proposed.The algorithm uses Julia set with cha-otic boundary as the key,and uses magic square scrambling to transform the key in the enlarged area of Julia set boundary to obtain the key image,combined with DNA random coding,the plaintext image is diffused to obtain the final ciphertext image.Julia set key only needs a few simple parameters to generate,which greatly reduces the storage space of the key.The chaos of Julia set makes the key change obviously with the slight modification of parameters,so it can not be decrypted normally.DNA random coding effectively solves the problem that a single coding method is vulnerable to plaintext attack.Simulation results show that the proposed algorithm has high security in key sensitivity,information entropy,anti noise and differential attack.
