An Image Encryption System by Indefinite Cellular Automata and Chaos

摘要：

In this paper a new image encryption system based on replacement of pixels values by using Indefinite Cellular Automata and chaos mapping is proposed. Cellular Automata rules sre defined based on chaos mapping and stored in private key. Proposed system have some advantages such as confusion, diffusion, sym metric private key, very large number of secret keys, key-dependent pixel value replacement and increasing system complexity with the impact of indefinite rules and chaos mapping.Simulation results obtained from the some images at the USC-SIPI database, demonstrate the strong performance of the proposed image encryption system.
