摘要
OSPF是一种典型的链路状态路由协议,是当前局域网中最常用的路由协议之一.文中简要介绍了OSPF协议的网络安全需求,提出了新的安全OSPF路由协议SOSPF,其中使用加密速度更快的公钥加密算法NTRU来实现OSPF协议的数字签名.采用NS-2平台对其进行仿真,并进行性能和安全性分析.
OSPF is a kind of link state route protocol, and is one of the most commonly used routing protocols in present local area network. In this paper, at first, the security demand of OSPF protocol is introduced in brief. Then a new security OSPF protocol-SOSPF is proposed. In the new protocol, NTRU is used to realize Digital Signature, which Encryption speed is faster than RSA. At last, NS- 2 platform is adopted to simulate them and make performance and security analysis.
