A novel parametric discrete chaos-based switching system for image encryption

This paper presents an efficient encryption technique for image. The designed chaos-based key generator provides a random and complex dynamic behavior and can change it automatically via a random-like switching rule. The proposed encryption scheme is called PDCSS (Parametric Discrete Chaos-based Switching System). The performances of this technique were evaluated in terms of data security. The originality of this new scheme is that it allows a low-cost image encryption for embedded systems applications. Simulation results have shown the effectiveness of this technique, and it can thereafter, ready for a hardware implementation.
