Research on Layered Security Protection Technology for Broadcasting and Television Multicast Networks
Currently,broadcasting and television multicast networks mostly adopt a one-way protection form,with a small coverage of security protection,which cannot achieve the expected protection effect.This article proposes a layered security protection technology for broadcasting and television multicast networks.Based on the current measurement requirements,first analyze multicast technology and layered security protection technology,then explore how to expand the security protection scope of broadcasting and television multicast networks-based on physical layer security protection,establish multi-dimensional protection conditions and environments using data link layer security protection and network layer security protection,and finally further expand the actual security protection effect through transmission layer security protection and application layer security protection,Strengthen the protection level of multicast networks and create a secure environment for the execution of broadcasting and television multicast tasks.
