Abstract: The network broadcast system of television is an important part of safe broadcast. The broadcast service has the characteristics of high flow, high bandwidth and low latency, and which brings new challenges to the traditional passive defense technologies, just like checking, killing, sealing and blocking. Based on trusted computing technology, this paper presents a security protection architecture with active defense ability for the network broadcast system of television and gives the realization methods of each key technologies, such as trusted measurement, trusted connection and signature verification. The proposed architecture can fundamentally ensure the security and accuracy of TV program production and broadcast, and guarantee the integrity and safe delivery of broadcast or business content. It also provides technical reference for improving the level of security protection of the network broadcast environment of television.
