摘要：

In this paper, a fast image encryption algorithm based on rows and columns switch is proposed. In the algorithm, the method of shuffling is rows switch and columns switch, and simultaneously the pixels of a row or column are encrypted by a key. A logistic map is used to generate the keys and the switched indexes of rows or columns. According to analysis, the number of iteration of logistic map is reduced, so the speed of the algorithm is faster. According to the data of researches, the speed of the algorithm is more than ten times than other algorithms. And this algorithm also has ideal character in withstanding differential attacks, statistical analysis, known-plaintext and chosen-plaintext attacks.
