Speaker: Dr. Liang Wang

Bio

Dr. Wang is an Associate Research Scholar at Princeton University. He received his  Ph.D. in Computer Science from the University of Wisconsin-Madison in 2018. His research interests lie in network security and privacy. His research focuses on using data-driven approaches to understand how major Internet components function in practice, identifying cross-boundary attacks, and developing practical and incrementally deployable defenses. His work was awarded the Caspar Bowden Award for Outstanding Research and Best Student Paper Runners-up at PETS 2022, and has been recognized in various ways (adoptions, invited talks, etc.) by industry leaders such as Google, Cloudflare, and Intel.

Abstract: The Internet ecosystem consists of various interconnected infrastructures, protocols, and services that depend on each other for seamless operation. Despite rigorous security analyses of individual components, security challenges can arise from interactions between components, necessitating a holistic approach to Internet security. This talk will explore security threats affecting major Internet components and the innovative defenses developed to mitigate these challenges. Specifically, I will demonstrate how cross-boundary attacks, such as traffic analysis, exploit encrypted network traffic to compromise the security and privacy of applications at higher layers, and introduce a novel defense mechanism to counter these risks. Additionally, I will discuss cross-layer routing attacks on Public Key Infrastructure (PKI), highlighting a practical defense that was successfully deployed at Let’s Encrypt and Google since 2020 and became an Internet standard in 2024. Through these case studies, I will illustrate the evolving landscape of Internet security and the importance of holistic security analysis.
