Image encryption using a new parametric switching chaotic system

• A new Parametric Switching Chaotic System (PSCS) is proposed by embedding three 1D chaotic maps.
• The 1D and 2D PSCS transforms are introduced for scrambling data streams and 2D data matrices.
• A PSCS-based image encryption algorithm is proposed.
• Simulations and analysis are provided to demonstrate the algorithm's encryption performance.

This paper introduces a new parametric switching chaotic system (PSCS) and its corresponding transforms for image encryption. The proposed PSCS has a simple structure and integrates the Logistic, Sine and Tent maps into one single system. The PSCS shows more general properties, including the Sine and Tent maps as special instances. It has complex chaotic behaviors. A novel image encryption algorithm is introduced using the proposed PSCS and its transforms. Simulation results and security analysis are given to demonstrate that the proposed algorithm can encrypt different types of images with a high level of security.
