Having Your Cake and Eating It Too: Routing Security with Privacy Protections
Internet Service Providers typically do not reveal details of their inter-domain routing policies due to security concerns, or for commercial or legal reasons. As a result, it is difficult to hold ISPs accountable for their contractual agreements. Existing solutions can check basic properties, e.g., whether route announcements correspond to valid routes, but they do not verify how these routes were chosen. In essence, today's Internet forces the users to choose between per-AS privacy and verifiability. In this paper, the authors argue that making this difficult tradeoff is unnecessary.
