直播卫星推送终端内容安全保护研究与实现

Research and Implementation of Content Security Protection for Live Broadcasting Satellite Push Terminals

本文针对直播卫星推送终端与内容保护前端无法交互的应用特点,提出适应直播卫星推送终端在卫星广播式环境下的内容保护方法,对推送终端中的直播、录制、推送等内容提供了安全的内容保护机制,使得直播卫星推送终端的存储内容、输出内容均为加密数据,具备接收密钥和分发密钥的能力,满足内容安全保护要求的前提下,实现推送终端和连接至本机的手机、PAD等客户端均能够解密并播放加密内容,有效保证内容提供者和使用者在内容安全保护和使用等方面的权益。

Because of the application characteristics that the live broadcasting satellite push terminal can't interact with the content protection front-end,this paper puts forward a content protection method that adapts to the live broadcasting satellite push terminal in the satellite broadcasting environment.It provides a secure content protection mechanism for the live broadcasting,recording,push,and other contents in the push terminal,so that the stored content and output content of the live broadcasting satellite push terminal is encrypted data,with the ability to receive and distribute secret keys.Under the premise of meeting the requirements of content security protection,the push terminal,mobile phones,PADs,and other clients connected to this machine can decrypt and play encrypted content,effectively ensuring the rights and interests of content providers and users in content security protection and use.
