Abstract

In this paper, we survey A5/1 and W7 stream ciphers as methods for protecting the distribution of digital images in an efficient and secure way. So, we performed a series of tests and some comparisons to justify their efficiency for image encryption. These tests included key space analysis, histogram analysis, Randomness Tests, information entropy, encryption quality, correlation analysis, differential analysis, sensitivity analysis and performance analysis. All parts of this study were simulated using MATLAB code. Based on all analysis and experimental results, it can be concluded that, the surveyed ciphers are efficient and Feasible with high potential to be adopted for image encryption.
