一种基于HLS的安全直播方案

A HLS-based Secure Live Broadcast Solution

结合HLS协议,提出了一种基于分布式的视频加扰方案。本方案提供两种不同的加密策略:预加密和实时加密,分别用来应对点播和直播业务。实验结果证明:相比传统的加密机视频加密的方案,本方案具有更好的可扩展性和更细的粒度控制,加密效果和加密性能更好。

Combined with HLS protocol,a distributed video encryption scheme is proposed.This solution provides two different encryption strategies:pre-encryption and real-time encryption,which are used to handle on-demand and live broadcast services,respectively.Compared with the traditional video encryption scheme,this solution has better scalability and fine-grained control.Experiments prove that this scheme has faster encryption speed and better encryption performance.
