Research on a Novel Image Encryption Scheme Based on the Hybrid of Chaotic Maps

This paper presents a novel image encryption scheme based on a hybrid of three order chaotic Chen system and piecewise linear chaotic map (PWLCM) The initial conditions and control parameters of chaotic systems are viewed as the secret key, and combined sequences from these two chaotic systems are employed to encrypt original image The proposed scheme is described in detail, along with experimental example and security analyses including sensitivity analysis, analysis of correlation of adjacent pixels and information entropy analysis The results show that the suggested scheme has some desirable properties in a good security cryptosystem.
