Information security in the tri-network convergence

With rapid development of Information technology and requirements on the information age, multi-network convergence has become the main trends in communication industry. In order to solve the information security risks in multi-network convergence, this paper researches the recent security risks in Broadcast and television network, Telecommunications network, and Internet (tri-network). However, the security problems in the tri-network have not been solved by traditional technologies. The paper regards the next-generation Broadcast and television network (NGB) as one of the solutions to the problems. It can be drawn from the research that, the Tri-network Convergence is imperative, and its environment could be protected by using NGB.
