Fast Image Encryption System Based on General Cat Map and Additive Modular Arithmetic
Wei Zhang · 2008
With the properties of sensitivity to initial conditions, control parameters and pseudo-randomness, 2D chaotic maps have been widely used in image encryption. This paper proposes a fast image encryption system, its process of confusion permutes a plain-image with general cat map, its process of diffusion is based on additive modular arithmetic, and it adopts the different key in every iteration.
