Secure Internet Routing : Where does your data go and who gets to see it along the way?

The Internet's routing system is supposed to ensure that every email, tweet and online banking request on the Internet is delivered to the correct destination; but the system is under constant attack. Through carelessness or malice, misuse of the routing system causes incorrect delivery of data to occur on a regular basis. Most of these attacks temporarily deny access to certain sites on the Internet. However, more sophisticated attacks can seamlessly alter the path that data takes, which changes who gets to see the data in transit.

In this talk, I first provide an overview of routing on the public Internet, and explain how the system is vulnerable to attack. I then describe my work in the development of new technology -- known as the Resource Public Key Infrastructure (RPKI) -- that utilizes cryptographic tools to fix vulnerabilities in the routing system.  Initial deployment of this technology is currently taking place in networks throughout the world. I conclude by discussing the challenges inherent in making substantial changes to the operation of the public Internet and possible approaches to overcoming those challenges.


Matt Lepinski received his Ph.D. in Computer Science from the Massachusetts Institute of Technology, and subsequently worked for 10 years as a research scientist in the network security department at BBN Technologies. He is currently an assistant professor at New College of Florida. His research focuses on the security and privacy of Internet protocols and the evolution of the public Internet.
