Research ArticleOpen accessIn the abstractA Shuffle Image-Encryption AlgorithmA. A. Yahya, A. M. AbdallaProblem statement: Image encryption needs to be secure by resisting statistical attacks and other types of attacks. Approach: The new algorithm, call it the Shuffle Encryption Algorithm (SEA), applies nonlinear s-box byte substitution. Then, it performed a shuffling operation partially dependent on the input data and uses the given key. Results: SEA was implemented and tested with different data, mainly … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Jul 2009 · 8,359 accessesView PDFCite
