摘要
OSPF(Open Shortest Path First)路由协议的路由表是基于LSA(Link State Advertisement)计算出来的,为了保证计算出的OSPF路由表是正确的,就应该对传输过程中的LSA信息的完整性和可靠性进行认证。分析了RFC2328的OSPF路由协议的认证机制,包括简单口令认证和加密身份认证,并介绍了基于数字签名的OSPF,对实现和应用OSPF路由协议的认证机制提供了参考。
OSPF (open shortest path first) routing table is calculated based on LSA (link state advertisement). For guaranteeing OSPF routing table correct, it's necessary to authenticate integrality and authenticity of LSA in transmission course. The authentication mechanism of OSPF in RFC2328 is analyzed including simple password authentication and cryptographic authentication, and OSPF with digital signatures is introduced. The reference of implementing and applying authentication mechanism of OSPF is offered.
