| 摘 要： | 提出一种新的视频实时加密算法RMVEA。RMVEA建立在数字多媒体实时动态系统上，独立于任何视频压缩算法，为实时数字视频提供高强度、高速度的加密。实验结果表明该锋法在基本不增加视频编码器负载及系统延时的情况下，能有效解决视频压缩率与密钥选择自由度的矛盾。

| Abstract: | This paper presents a novel real-time MPEG video encryption algorithm called RMVEA. RMVEA is based on real-time digital multimedia system and is independent of any video compression algorithm. It offers encryption of high intensity for real-time digital video. It provides fast speed of encryption and can be implemented simply by software or hardware. RMVEA adds minimum overhead to codec and can make a good balance between compress ratio and key selection freedom. Experimental results show that RMVEA achieves satisfying results. |
