| 摘 要： | 基于混沌映像格子(CML)提出了一种新颖的图像保密通信方案.发送方利用CML快速产生二值时空混沌序列,并将其与原始图像进行异或加密处理,经通信双方同步后,接收方即可解密出原始图像.由于混沌序列对CMI.中的耦合系数、驱动序列初值等比较敏感,增加了序列抗攻击能力.数值实验结果表明本方案是可行的,并对系统密钥空间、密钥敏感性等密码学特性进行了分析. |

| Abstract: | Based on chaotic map lattices (CML),a novel image secure communication scheme is proposed.In this scheme,the spatiotemporal binary sequences are rapidly generated and will be used to encrypt source image by exploi- ting bit-wise xor operation.Once the synchronization of the communication between the sender and receiver is satisfied, the encrypted image then can be correctly recovered into source image.As the chaotic sequences are very sensitive to the coupled parameter of CML and the initial value of the dr... |
