- Abstract
In order to solve these defects such as poor performance of cipher random as well as anti-attack induced by the obtained sequence aren't dependent on the plaintext and separately encrypting RGB pixel in current color image encryption systems, this paper proposed the lossless synchronously encryption algorithm of color image RGB components based on extraction plaintext information coupled multi-chaotic pixel shuffle. Firstly, it performed the operation of the color image RGB pixels separation, binarization and vectorization to get the three vectors of RGB, and regrouped theses vectors to obtain the permutation matrix of RGB pixels interaction. Then it extracted the image information to control iterative processes of four super-chaotic systems for making the random sequence associated with the plaintext, and used these random sequences to encrypt the permutation matrix by shuffling column-wise and row-wise. Simulation results show that compared with other color image encryption algorithm, this algorithm has higher security and larger key space, as well as strong key sensitive performance. This algorithm has high security, and it can meet the actual engineering requirements.
