One kind of secure video transportation scheme

为使视频不被非法使用,需要对视频提供加密。文章描述了所涉及到的身份认证、数据完整性、媒体流加密、不可否认性等方面的问题,提出了一种嵌入式视频加密服务器的设计方案。

In order to ensure the security of multimedia communication of H.323 system, Recommendation H.235, produced by ITU-T, should be used within the framework of the H.323 to incorporate security services.The paper first describes the main security services referred by Recommendation H.235, such as authentication, integrity, media stream privacy and Non-Repudiation.A embedded secure video was designed , and the system and design principles were described, at last the transmit protocol was discussed.
