A Polytheistic Approach to Secure Interdomain Routing

The large body of research on interdomain routing security has had little real-world impact despite the immense importance of the subject. I observe that the community seems to be in search of “the one” – a perfect solution in terms of security, deployment costs, deployment incentives, and transition complexity. This perfect solution is expected to be attractive to all ISPs and fit the needs of all ISPs. Many such “monotheistic” solutions have been proposed by various researchers, and new ones continue to exhaust the remaining design possibilities.
