摘要
数字视频广播(DVB)技术可用于提供基于互联网协议(IP)的服务以及音频和视频广播。IETF为在DVB上传输IP数据报定义了一种新的协议,称为单向轻量级协议(ULE)。与DVB中用于传输IP数据的现有机制相比,ULE提供了几个优点。本文描述了ULE协议的扩展,为DVB上的IP服务提供安全保障。讨论了IP over DVB业务的不同安全要求。描述了ULE满足这些需求的机制和安全性扩展。仿真结果显示了这些安全机制对IP流量的影响
Design and analysis of secure transmission of IP over DVB-S/RCS satellite systems
Digital video broadcasting (DVB) technology can be used for providing Internet protocol (IP) based services along with audio and video broadcasting. A new protocol, called unidirectional lightweight protocol (ULE) has been defined by the IETF for the transport of IP datagrams over DVB. ULE provides several benefits over the existing mechanisms used in DVB for transporting IP data. This paper describes an extension to the ULE protocol to provide security for IP services over DVB. The different security requirements for IP over DVB services are discussed. The mechanisms and security extensions for ULE to satisfy these requirements are described. Simulation results are also presented to show the impact of these security mechanisms on the IP traffic
