摘要

用于在因特网上传播路由信息的路由协议不受入侵者或有故障的路由器参与者的保护。本文报告了通过使用密码学，特别是数字签名来保护OSPF路由协议的工作进展。路由信息用非对称加密算法签名，允许每个路由器接收方检查信息的来源和完整性。本文讨论了路由协议安全的基本问题，回顾了OSPF运行的基础，描述了提议的设计，并讨论了存在的漏洞。

Digital signature protection of the OSPF routing protocol

The routing protocols used to disseminate routing information throughout the Internet are not protected from intruders or faulty router participants. This paper reports on work in progress to protect the OSPF routing protocol through the use of cryptography, specifically, digital signatures. The routing information is signed with an asymmetric cryptographic algorithm, allowing each router recipient to check the source and integrity of the information. This paper discusses the fundamental issues in security of routing protocols, reviews the basics of OSPF operation, describes the proposed design and discusses remaining vulnerabilities.
