Addressing Security Issues in the Border Gateway Protocol

چکیده
The Internet is a critical component in today’s society. This makes it ever so important to have a secure routing protocol. In the current Internet routing protocol, BGP, security was only an afterthought as it was designed on the basis of trust. With trust, misconfigurations and attacks can disrupt the Internet easily. Therefore, many proposals have been made to make BGP more secure. In this paper, we explain what attacks can occur, then perform a survey of many types of proposals that have been presented in the past. We lastly present our ideas to secure the BGP protocol. We believe that the key of success for the BGP protocol is to provide one with the characteristics of backwards compatibility of the existing version, scalability, enhancement of security, and easy deployment. These features are the goals of the protocol we present in this paper. Our ideas guard the AS Path from alterations using cumulative authentication and then make sure that the origin AS is able to advertise the prefixes.

Border Gateway Protocol (BGP), the only standard for interdomain routing in the Internet, is used to exchange information between Autonomous Systems (ASes). BGP possesses many security vulnerabilities, as it works with the information received from the neighboring routers, and neighbors can lie, deliberately or mistakenly. Many security approaches have been proposed, but due to reasons like inc...

Internet security and stability are topics we keep returning to in this journal. So far we have mainly focused on technologies that protect systems from unauthorized access and ensure that data in transit over wired or wireless networks cannot be intercepted. We have discussed security-enhanced versions of many of the Internet core protocols, including the Border Gateway Protocol (BGP), Simple ...
