Color Image Encryption Algorithm Based on DNA Encoding And Memristor Chaotic System

In image encryption, in order to help the image resist the known plaintext attack, selective plaintext attack and differential attack, and improve the singularity of DNA coding algorithm, the association of plaintext, ciphertext and chaotic initial value is proposed, as well as the iterative operation combining plaintext, ciphertext and chaotic sequence in DNA operation. After encryption, through the analysis of histogram, correlation coefficient, information entropy, plaintext sensitivity and other aspects, it is proved that the algorithm can well resist differential attacks and select plaintext attacks, and image encryption is more secure.
