广播电视组播网络分层式安全防护技术研究

Research on Layered Security Protection Technology for Broadcasting and Television Multicast Networks

目前的广播电视组播网络多采用单向的防护形式,安全防护覆盖范围较小,无法达到预期的防护效果。为此文章提出广播电视组播网络分层式安全防护技术。根据当前测定需求,先对组播技术和分层式安全防护技术进行分析,接着探究如何扩大对广播电视组播网络的安全防护范围——以物理层安全防护为基础,采用数据链路层安全防护和网络层安全防护进行多维防护条件和环境建立,最终通过传输层安全防护与应用层安全防护进一步扩展实际安全防护效果,强化组播网络的防护等级,为广播电视组播任务的执行营造安全环境。

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.
