This document species Trivium, a hardware oriented synchronous stream cipher which aims to provide a exible trade-o between speed and area. The descr iption of the cipher is followed by some performance gures and a summary of the cryptogr

本文通过VC技术实现了数字图像水印LSB算法 ，嵌入与提取密钥是对称密钥算法中的序列密码算法。通过设计可以方便地在宿主图像中嵌人大量数字信息 ，在嵌入水 印容量上能实现较高容量和在最低位嵌入时有较好的不可见性。LSB算法的优点是其算法简单，计算速度比较快。但是对图像的各种操作如压缩、剪切等 ，都会使算法的可靠性受到影响，也有可能通过噪声增加或有损 压缩而消除水印，即鲁棒性较差 。　 -In this paper, VC technology LSB algorithm of digital im

This paper addresses the usage of FCSR in place of LFSR in a stream cipher. To demonstrate the usage ZUC stream cipher is taken as example in this paper. A good stream cipher should have good randomness, high period, linear span, and security aga
