中文摘要：

一个新奇录像数据认证模型基于数字录像 watermarking 和 MAC (消息认证代码) 在多点传送协议在这篇论文被建议。重要录像内容，钥匙和立刻的认证数据的 MAC 创作的数字 watermarking 被 MLUT (修改 look-uptable ) 嵌进不足道的录像部件录像 watermarking 技术。我们解释不在一时间要求每个数据包的存储的一个方法，因此使接收装置不脆弱到 DOS (拒绝服务) 攻击。没有大卷缓冲区， Sothe 录像包能在接收装置立即被证实。泰斯拉(预定有效溪流损失容忍的认证) 不解释怎么为 d 选择合适的值，它是一个重要参数在多点传送来源认证。我们因此给一个方法计算关键揭发延期(间隔的数字) 。模拟结果证明建议算法改进数据来源认证的表演在多点传送。

英文摘要：

A novel video data authentication model based on digital video watermarking and MAC （message authentication code） in multicast protocol is proposed in this paper, The digital watermarking which composes of the MAC of the significant vid eo content, the key and instant authentication data is embedded into the insignificant video component by the MLUT （modified look-up table） video watermarking technology. We explain a method that does not require storage of each data packet for a time, thus making receiver not vulnerable to DOS （denial of service） attack. So the video packets can be authenticated instantly without large volume buffer in the receivers. TESLA （timed efficient stream loss tolerant authentication） does not explain how to select the suitable value for d, which is an important parameter in multicast source authentication. So we give a method to calculate the key disclosure delay （number of intervals）. Simulation results show that the proposed algorithms improve the performance of data source authentication in multicast.
