The encryption algorithm significantly reduces correlation coefficients from 1 in the original image to 0 in the encrypted image, while maintaining NPCR (Number of Pixel Change Rate) and UACI (Unified Average Changing Intensity) values within the critical range. Additionally, both theoretical analysis ...

A kind of image encryption algorithm is presented based on chaos theory and cycle shift. Firstly a chaos sequence is generated, then the pre-encrypted image based on XOR operation and cycle shift is obtained, and encrypted image is achieved by Arnold mapping on the pre-encrypted image, The ex...
A novel image encryption algorithm based on the dynamical chaotic system is proposed in this paper. This image cryptosystem employs a new circular inter–intra pixels bit-level permutation-based confusion strategy. This strategy has considerably reduced the redundancies of Fridrich's structure-based encr...
