NEW IMAGE ENCRYPTION/DECRYPTION ALGORITHMS BASED OF CHAOS

Abstract

In recent years, owing to the great development of communication system and multimedia technology, the digital images can be altered and destroyed by the illegal user easily. Hence, image data security has become a critical issue. This paper is intended to propose some image encryption/decryption algorithms by taking advantage of the features of the chaotic sequences. The computational complexity and security level of proposed image encryption/decryption algorithms are analyzed. Finally, the simulation results and their fractal dimensions are given to demonstrate the effectiveness of the proposed schemes.
