zishiyingjiami
- 为了提高图像加密算法的鲁棒性，提出了一种新的自适应图像加密算法。首先，把任意大小的灰度或彩 色图像分成2 × 2 子块 然后，用左上角子块的像素灰度值和Chebyshev 混沌映射构造与右上角子块等大的矩阵，用该 矩阵对右上角子块进行像素灰度值替换 最后，按顺时针对每个子块进行加密，直到左上角子块加密完毕。该算法不 依赖于图像的大小，而且适用于灰度图像和彩色图像，因而有很强的鲁棒性。同时灰度值扩散机制的引入使得该算 法具有良好的扩散性和扰乱性。-This paper presen
MerkleHellman
- The encryption algorithm using Merkle-Hellman knapsacks starts with a binary message. * The message is envisioned as a binary sequence P = [p1, p2, … ,pk]. * Divide the message into blocks of m bits, Po = [P1, P2, ... ,Pm], P1 = [Pm+1, .
