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. In order to check the efficiency of proposed method, the new encryption scheme is compared with two current classes of stream ciphers: W 7 and Salsa 20. So, we performed a series of tests and some comparisons to justify efficiency of image encryption methods. These tests included key space analysis, psycho-physical experiments, histogram analysis, information entropy, encryption quality, correlation analysis, differential analysis and sensitivity analysis. Simulation experiment has validated the effectiveness of the proposed system.
