Abstract
Image encryption is a crucial area for researchers in information security, which protects digital images from unauthorized access. This paper proposes a novel image encryption scheme based on the multi-chaotic system. This paper is about encrypting color images based on a 2D Henon map and a 3D Lorenz map. We used the 2D Henon map equation to generate a new S-Box, thus creating a solid cipher that is difficult to break (for the confusion operation). We then generate keys from the 3D Lorenz map for the shifting process (for diffusion operation). A comparative analysis and the simulation test show that the suggested image cryptosystem has some excellent properties, including high sensitivity, fast encryption/decryption, a large keys-pace, excellent statistical properties related to the ciphertext, etc.
