Abstract
A novel video multicast instant source authentication model based on digital video watermarking and TESLA (Timed Efficient Stream Loss-tolerant Authentication) protocol is proposed in this paper. The digital watermark, which composes of the MAC (Message Authentication Code) of the significant video content, the key and instant authentication data, is embedded into the insignificant video component by the MLUT (Modified Look-Up Table) video watermarking technology. So the video packets can be authenticated instantly without large volume buffer in the receivers. In addition, we give a method to calculate the key disclosure delay (number of intervals).
