CHAU Sze Yiu 周思驍教授
Sze Yiu joined the Department of Information Engineering at CUHK as an Assistant Professor in January 2020. He obtained his Ph.D. in Computer Science from Purdue University in August 2019, and has industry R&D experience working for Intel. Prior to joining CUHK, Sze Yiu was a postdoctoral researcher at the CyLab Security & Privacy Institute at Carnegie Mellon University. He received his B.Sc. from The Hong Kong Polytechnic University in 2013.
His research interest is mainly on the (in)security of the design and implementation of cryptographic and network protocols. He and his colleagues have substantial experience in analyzing and breaking protocol implementations, with a specific focus on issues related to semantic correctness. His research has discovered numerous weaknesses in widely deployed software systems, including content delivery apps on Android, as well as cryptographic libraries implementing X.509 certificate validation and RSA signature verification, where many of the discoveries are exploitable and deemed highly severe. He is also very interested in applying reasoning techniques backed by formal logic into solving real-world security and privacy challenges.
