| 摘 要： | 在不移动像素情况下达到对图像进行加密目的，提出一种基于图像位平面的加密算法。按像素比特位对图像进行分解，得到图像位平面，再利用两个Logistic混沌系统构造二值矩阵与中间密钥矩阵对位平面执行置乱加密，最后将各个位平面叠加得到密文图像。

| Abstract: | In order to realize the purpose of encrypting image while not moving its pixels, a new encryption algorithm based on bit-plane is presented. In this algorithm, the image according to the pixel bits is decomposed into bit-planes, and two logistic chaotic systems is used to generate a binary matrix with a number of intermediate key matrixes to perform scrambling encryption in the bit-planes. Then each bit-plane is superimposed to get the encrypted image. |
