The S-Boxes with high nonlinearity and low differential uniformity are highly desirable for designing a secure image encryption scheme to ensure secure communication of digital images over the Internet. This paper presents a novel image cryptosystem using key-dependent bijective S-Boxes based on the Henon map. In this paper, the 2D Henon-map is used to generate key dependent bijective S-Boxes (for confusion) and pseudo-random sequence (for diffusion) to design a color image cryptosystem with high confusion and diffusion capability. We perform the security analysis of the proposed encryption scheme and the experimental results shows that the proposed image encryption scheme is able to resist the statistical attack (entropy and NIST randomness test), differential attack (NPCR and UACI), correlation and chosen-plaintext attack.
