| 摘 要： | 基于数字水印和TESLA,提出了一种视频多点广播立即源认证模型,利用查找表的视频水印算法,将视频重要分量的消息认证码、公开密钥和立即认证散列值等嵌入到视频的非重要分量中;从而达到视频数据多点广播的立即源认证,避免了接收方数据包缓存,并给出公开延迟时间间隔d的一种计算方法。

| Abstract: | A novel video multicast instant source authentication model based on digital watermarking and TESLA (Timed Efficient Stream Loss-Tolerant Authentication) is proposed in this paper. With the Modified Look Up Table video watermarking algorithm, the digital watermark, which composes of the Message Authentication Code(MAC) of the significant data, public key and instant authentication data, is embedded into the insignificant video data. The video packages can be authenticated instantly by the use of MAC and instant authentication data without large volume buffer in the receivers. In addition, a method is provided to calculate the key disclosure delay (number of intervals). |
