【摘要】 OSPF路由协议是网络上应用最为广泛的链路状态协议之一,用于在网络上分发路由信息,但是这个担负着因特网上路由信息分发任务的重要协议在其制定之初并没有有效的安全手段.为此,IETF提出了数字签名保护的OSPF路由协议.阐述了数字签名保护的OSPF协议的设计思想和实现技术,构筑了带数字签名保护功能的路由器组成的实验网络,对路由协议的数字签名方案进行了仿真试验并得到了系统的数据,在此基础上分析了数字签名保护的OSPF协议的安全特性.更多还原

【Abstract】 OSPF routing protocol is one of the most popular link-state protocol.The routing protocol which is used to disseminate routing information throughout the Internet is not protected from intruders or faulty routers.For these reasons,the IETF add a digital signature protection to the OSPF.This paper analyses the secure characteristics and the implementation of the OSPF routing protocol with digital signature protection,construct a route network with four digital signature protection’s OSPF router.And analyzes these data which achieved from the experiment.更多还原
