The lack of accountability makes the Internet vulnerable to numerous attacks, including prefix hijacking, route forgery, source address spoofing, and DoS flooding attacks. This work takes a "dirty-slate" approach to bring accountability to the present Internet with low-cost and deployable enhancements. In this talk, we will present IPA, a network architecture that uses the readily available top-level DNSSEC infrastructure and BGP to bootstrap accountability. We integrate IPA with a suite of security building blocks to combat various network-layer attacks. Our evaluation shows that IPA introduces modest overhead, is gradually deployable, and offers security incentives to early adopters.
