CS Colloquium: Yixin Sun (Princeton University) - Providing secure Internet services with insecure infrastructure

Speaker: Yixin Sun, Princeton University
Talk Title: Providing secure Internet services with insecure infrastructure
Series: CS Colloquium
Abstract: The insecurity of Internet services can lead to disastrous consequences -“ confidential communications can be monitored, financial information can be stolen, and our critical Internet infrastructure can be crippled. However, many prior works on Internet services only focus on the security of an individual network layer in isolation, whereas the adversaries do quite the opposite -“ they look for opportunities to exploit the interactions across heterogeneous components and layers to compromise the system security. This gap leaves the privacy and security of billions of users as well as our critical infrastructure at risk.
I aim to bridge this gap to build privacy-preserving and secure Internet services. In this talk, I will focus on two Internet services, the Tor network and the Public Key Infrastructure. I have uncovered new vulnerabilities in these services by taking a cross-layer approach to exploit the interdependencies across different network layers. I have demonstrated attacks in the wild (ethically) to evaluate the real effects of vulnerabilities. Consequently, I have built practical defenses that have received real-world deployment by the Tor Project which serves millions of users, and Let's Encrypt which is the world's largest Certificate Authority that has issued hundreds of millions of digital certificates.
This lecture satisfies requirements for CSCI 591: Research Colloquium.
Biography: Yixin Sun is a PhD candidate in Computer Science at Princeton University. Her research focuses on building privacy-preserving and secure networked systems. She received the Information Controls Fellowship from the Open Technology Fund, the SEAS Award for Excellence from Princeton, and the EECS rising star from MIT. Throughout her career, Yixin has collaborated with many industrial labs and non-profit organizations, such as the Tor Project, Let's Encrypt, Verisign Labs, NEC Labs and International Computer Science Institute (ICSI). Previously, Yixin received her Bachelor's degree in Computer Science and Mathematics from the University of Virginia.

CS Colloquium: Amy Babay (Johns Hopkins University) - Dependable Systems and Networks for a Complex World
Thu, Apr 04, 2019 @ 11:00 AM - 12:00 PM
Thomas Lord Department of Computer Science

Speaker: Amy Babay, Johns Hopkins University
Talk Title: Dependable Systems and Networks for a Complex World
Series: CS Colloquium
Abstract: As our world grows more complex, the expectations we place on the networked systems running our society's infrastructure grow more demanding. In this talk, I will discuss two types of emerging demands and present infrastructure systems we have developed to meet those demands. The first part of the talk will focus on the demanding performance requirements brought by emerging highly interactive applications such as remote robotic manipulation, remote surgery, and collaborative virtual reality. These applications require communication that is both timely and highly reliable, but the Internet natively supports only communication that is either completely reliable with no timeliness guarantees (e.g. TCP) or timely with only best-effort reliability (e.g. UDP). We present an overlay transport service that can provide highly reliable communication while meeting the stringent timeliness requirements of these applications. The second part of the talk will address the demanding security and resilience needs of critical infrastructure services, in particular SCADA systems for the power grid, that are increasingly becoming exposed to malicious attacks. I will present our work building Spire, the first intrusion-tolerant SCADA system for the power grid that is resilient to both system-level compromises and sophisticated network-level attacks.
This lecture satisfies requirements for CSCI 591: Research Colloquium.
Biography: Amy Babay recently completed her PhD in Computer Science at Johns Hopkins University, where she was a member of the Distributed Systems and Networks Lab. Her research focuses on enabling new Internet services with demanding performance requirements and on building dependable critical infrastructure systems. Prior to starting her PhD, she gained experience with global overlay networks in the commercial world, working at LTN Global Communications. She is currently working to advance some of her research toward commercialization at Spread Concepts LLC.
