摘要

文章分析了边界网关协议BGP4的安全弱点

针对这些安全弱点对协议进行了扩展.通过数字签名技术来保护AS

PATH属性中的信息.为了适应分布式路由协议的特点

提出了分布式的基于RSA的密钥生成算法.通过综合运用这些技术

在基本保持报文长度不变的情况下有效地保护了BGP协议信息的机密性、可信性和完整性.

Abstract

The security weakness of Border Gateway Protocol (BGP-4) is analyzed.Aiming at the weakness

the protocol are extended with some security properties.Digital signature mechanism is used to protect the AS

PATH information.To satisfy the characteristic of distributed routing protocol

a distributed key generation algorithm based on RSA is presented.By integrating these techniques

confidentiality

creditability and integrity of BGP are protected in keeping the packet length with near constant space.
