Securing Domain Validation

This project secures Internet domain validation against attackers that manipulate Internet routing via Border Gateway Protocol (BGP) hijack and interception attacks.

Background: The Public Key Infrastructure protects users from malicious man-in-the-middle attacks by having trusted Certificate Authorities vouch for the identity of servers on the Internet through digitally signed certificates - usually displayed to users on their Internet browser via a small padlock icon near the address bar. Ironically, the mechanism that Certificate Authorities use to issue certificates (domain validation) is itself vulnerable to man-in-the-middle attacks by network-level adversaries.

This project analyzed the attack surface of domain validation against BGP-based attacks, designed countermeasures to secure domain validation protocols, and deployed them in real-world production systems such as Let's Encrypt and Cloudflare. This provides protection from these attacks to hundreds of millions of websites around the globe.
