TLS in Practice: TLS and Research Topics

Thursday 28 September 2023
Niels Bohrweg 1
2333 CA Leiden

The TLS protocol is the most widely used security protocol on the Internet. Due to its popularity, TLS has been extensively studied with regard to adoption in diverse environments, formal verification, middlebox compatibility, performance enhancement, and so on.

In this talk, I will briefly introduce the protocol with its related research topics. In particular, I will talk about the TLS extension that makes itself compatible with network middleboxes, security analysis of TLS 1.3 in practice, and performance enhancement of TLS 1.3


Hyunwoo Lee is an assistant professor in the department of energy engineering at Korea Institute of Energy Technology (KENTECH). Before joining KENTECH, he was working as a postdoc research associate under Prof. Elisa Bertino and Prof. Ninghui Li at Purdue University researching security verification of mobile network protocols and AI-based intrusion detection systems. He received B.S. and Ph D. in the department of computer science and engineering at Seoul National University. 

His research interests lie in a broad range of network security including security verification of network protocols (e.g., TLS or mobile network protocols), design and implementation of new security protocols (e.g., TLS extensions), and AI-based network security (e.g., self-evolving IDS systems).
