Abstract

The invention discloses a color image encryption algorithm based on DNA coding and double-chaotic mapping, randomness of a chaotic sequence is greatly improved by adopting an improved Lorenz chaotic system and a random sequence generated by a four-order Rossler chaotic system, and randomness of the random sequence is compensated by the double-chaotic systems. A DNA encoding rule is introduced intoan image encryption algorithm based on the model, so that bit-level diffusion operation of the color image is realized, the safety performance of the encryption scheme is improved, and time complexity of the encryption algorithm is reduced by utilizing a sequential bit-level encryption algorithm. Compared with other chaotic encryption algorithms, the image encryption algorithm provided by the invention has higher security and attack resistance, and is very suitable for encryption and protection of multimedia images.

Description

technical field

[0001] The invention relates to the field of bit-level DNA calculation for color image encryption, in particular to a color image encryption algorithm based on DNA coding and a double chaotic system. Background technique

[0002] The rapid development of the Internet has created a new era in the fields of global economy, culture, military affairs, and education. In the new era, people can easily realize the transmission of image information. However, digital images may involve private or confidential information, which, if leaked, could have immeasurable consequences. The most commonly used method to protect the security of image information is image encryption. Traditional encryption techniques, such as DES, AES, RSA, etc., are not suitable for image encryption, and the application of image encryption will lead to low system efficiency and poor security.

[0003] Chaotic systems have the characteristics of complexity, determinism and nonlinearity. It has...
