RE: Do Not Complicate Routing Security with Voodoo Economics

Sorry, I was misunderstood. To clarify, I was referring only to our work (, where security does play a small role in the route selection process (after LocalPref and AS-PATH length), and not to the BGPsec spec. The reason why we assume that security affects the route selection process is because otherwise, even an AS that deploys S*BGP, remains vulnerable to attacks. To see why, take a look at slides 10-13 of our NANOG presentation (, video available at The basic idea is: if an AS prefers short paths over secure paths they'll be just as vulnerable to path-shortening attacks with and without S*BGP.
