| 摘 要： | 针对流媒体的非法复制和传播问题,分析了流媒体的特点,对CA的加密思想进行改进。方法是使用三级密钥加密,并在加扰器之前添加了数据包选择器,使其只选择一部分数据包进行加扰,从而形成了一种应用在流媒体DRM中的选择性三级密钥加密方案。

| Abstract: | To solve the problems of illegal copying and dissemination of the streaming media,on the basis of analyzing the characteristics of streaming media,encryption mechanism of CA was improved.A triple-level key was used to encrypt data streams and a packet-chooser was added before scrambler to make the packet-chooser chose part of the packets to be scrambled.Then a selective triple-level key mechanism for streaming media was built in DRM. |
