Abstract

This work presents a chaotic image encryption algorithm that acts on the binary level of the image for effective permutation, and on the byte level for substitution. The permutation step combines actions of bit plane rearranging, and bit shuffling via circular shift operations, to reduce the execution time. For the encryption, a Soboleva hyperbolic tangent based map is used, along with a chaotic pseudo random number generator. The encryption process shows a good performance under various tests, and has also a low execution time, 0.0145s for a 256 × 256 image, and 0.0565s for a 512 × 512 image.
