摘要
根据视频压缩标准H.264的原理和特点,提出了一种用动态密钥对视频信息进行选择性加密的新方法。该算法利用动态密钥加密视频信息的关键部分,既保证了视频信息的安全性,又提高了传输速率。算法在H.264参考软件JM12.4上加以实现,实验结果表明,算法达到了理想的加密效果。
A new method for using dynamic key to encrypt video information is put forward based on the theory and characteristics of H.264 video compression standard. The dynamic key encrypts the key part of video information, not only to ensure the safety of the video information, but also to improve the transmission rate. The algorithm is implemented in JM12.4, and the experimental results show that the new algorithm of encryption can achieve the ideal effect.
