| 摘 要： | 文中主要介绍了一种基于行程长的无损选择加密方法，首先对图像住平面采用行程长编码，再过滤掉对图像的主体部分不构成影响的短行程，使得所需加密的内容减少，然后对所选的内容进行AES或者基于LFSR的流密码加密，最后对加密方案作了安全性评估，表明这是一个快速安全的选择加密算法．

| Abstract: | A selective encryption algorithm based on Run-length Encoding with no loss is proposed in this paper. First the bitplane is run-length encoded, and then the short run-length, which is not important to the image is filtered off, thus reducing the encryption content. The selected content is encrypted with AES or stream cipher based on LFSR. Finally the security of the algorithm is analysed, and it is proved to be a secure and fast algorithm. |
