About me

Welcome to Chaoyun Li's (李超云) web page. I am a Lecturer in the Surrey Centre for Cyber Security at University of Surrey. Previously, I was a postdoc researcher at COSIC, KU Leuven from 2020 to 2023. I obtained my PhD degree in cryptography from COSIC in February 2020 under the supervision of Prof. Bart Preneel. My research interests include cryptography, security and privacy. I have been working on the following topics:
  • Applied Cryptography
  • Privacy Enhancing Technologies
  • Discrete Structures: sequences and Boolean functions

PhD thesis: New Methods for Symmetric Cryptography
