The inter-domain routing protocol, Border Gateway Protocol (BGP), plays a critical role in the reliability of the Internet routing system, but forged routes generated by malicious attacks or mis-configurations may devastate the system. The security problem of BGP has attracted considerable attention, and although several solutions have been proposed, none of them have been widely deployed due to weaknesses such as high computational cost or potential security compromise. This paper proposes Fast Secure BGP (FS-BGP), an efficient mechanism for securing AS paths and preventing prefix hijacking by signing critical AS path segments.
