摘要我们设计，实施和评估CovertCast，一个审查规避系统，在常见的直播服务，如YouTube上实时播放流行网站的内容，加密视频流。CovertCast不需要对流媒体服务进行任何修改，并且使用与该服务的任何其他用户相同的协议，服务器和流媒体软件。因此，无法通过IP地址过滤或协议指纹识别将CovertCast与其他直播流区分开来，从而提高了审查者的门槛。
Abstract We design, implement, and evaluate CovertCast, a censorship circumvention system that broadcasts the content of popular websites in real-time, encrypted video streams on common live-streaming services such as YouTube. CovertCast does not require any modifications to the streaming service and employs the same protocols, servers, and streaming software as any other user of the service. Therefore, CovertCast cannot be distinguished from other live streams by IP address filtering or protocol fingerprinting, raising the bar for censors.
