Abstract
Information security is one of the most important defensive issues that prevents the intruders' attacks to the privacy of organizations valuable data. Cryptology is one of the most powerful tools of Passive defence that assures the security of communication and information technology. In this paper, we propose a new image encryption scheme using chaotic maps to protect the distribution of digital images in an efficient and secure way. The new encryption scheme is implemented using MATLAB to check its efficiency. Moreover,A series of tests and some comparisons have been performed to justify efficiency of image encryption method. These tests included key space analysis, psychophysical experiments, histogram analysis, information entropy, encryption quality, correlation analysis, differential analysis and key sensitivity analysis. Simulation experiment has validated the effectiveness of the proposed system.
