Duration:60 Minutes
The state of Internet security today is largely reactive, continually raising the defensive bar in response to increasingly sophisticated
attackers. In this talk, I will present an alternate approach to building Internet systems that underlies much of my work: instead of
reactively working around some attacks, what if we were to make them impossible in the first place?

 I will discuss two primitives my collaborators and I have created that provide small proofs of impossibility, and I will demonstrate
  how they can be applied to solve large-scale problems, including censorship resistance, digital currency, and online voting.  
  First, I will present TrInc, a small piece of trusted hardware that provides proof that an attacker could not have sent conflicting
  messages to others.  Second, I will present Alibi Routing, a peer-to-peer system that provides proof that a user's packets could
  not have gone through a region of the world the user requested them to forbid. Finally, I will describe some of my ongoing
  and future efforts, including securing the Web's public key infrastructure.
