Color quantum image encryption and decryption method based on multi-chaos and dna operation

Abstract

The invention provides a color quantum image encryption and decryption method based on multi-chaos and DNA operations, comprising: using a random key and a hash value calculated from the original plaintext image as an encryption key, and using the encryption key to generate a five-dimensional hyperchaotic system Initial value and generate chaotic sequence, and use DNA coding to convert chaotic sequence into DNA sequence; use super Lorenz chaotic map and encryption parameters obtained by random number generator to generate encrypted chaotic sequence; use quantum image representation model to convert encrypted chaotic sequence and original plaintext Convert the image into encrypted quantum chaotic sequence and original quantum image; use encrypted quantum chaotic sequence to perform CNOT operation on original quantum image to obtain scrambled quantum image; use encrypted quantum chaotic sequence and encrypted DNA sequence to perform DNA diffusion operation on scrambled quantum image, Get encrypted image. The encryption method of the present invention is separated from the category of classical computers and improves the security of the encryption algorithm.

Description

technical field [0001] The invention relates to the technical field of image encryption, in particular to a color quantum image encryption and decryption method based on multi-chaos and DNA operations. Background technique [0002] In the current Internet era, with the rapid development of multimedia and communication means, image transmission has become one of the most popular and basic means of multimedia. Not only the protection of personal privacy, but also at the national level, the privacy of secret information is also very important. The traditional AES and DES encryption technology can only encrypt text data, not suitable for images. [0003] With the introduction of quantum computers, the security of encryption algorithms based on classical computers is greatly reduced due to its efficient quantum parallel computing characteristics. [0004] The field of quantum image encryption is on the rise. However, at present, one of the encryption algorithms based on quantu...

Problems solved by technology

However, at present, one of the encryption algorithms based on quantum images is quantum scrambling based on Arnold, Fibonacci transformation and Hilbert scanning matrix. The disadvantage of slow speed; one is the quantum scrambling method combining gray code and qubit, the encryption method is single, and the encryption effect is not good
