摘要
提出了一种基于 m序列的图像随机加密与实时传输方案。在加密时用 m序列构造的相位函数取代了双相位编码方法中用作密钥的随机相位掩模 ,极大地压缩了密钥的数据量 ,使密钥的传送更加方便快捷。并在前有基础上加以改进 ,可以轻松地加密彩色图像。在完成加密后 ,可实时地在网络上传送加密图像 ,在接收端进行解密。最后进行了计算机模拟实验 ,实验结果表明该方案是可行的 。
Presents an image random encryption and real time transmission scheme Instead of random phase, phase function produced by msequence is used as encryption key It compresses the data of key greatly, make the key easier to be transmitted And in this scheme, the encrypted image could be transmitted on Internet in real time for decryption Finally, computer simulation is performed, the results show the scheme is feasible Furthermore it is convenient for application
