My name is Wu Ka Lok, Cousin (also known as Cosine, usin, …). I am a second-year MPhil student (looking for PhD advisors!) in the Department of Information Engineering at the Chinese University of Hong Kong (CUHK), under the supervision of Prof. Sze Yiu Chau. Before that, I was an undergraduate majoring in Mathematics (Pure Mathematics (Advanced)) and Computer Science at the Hong Kong University of Science and Technology (HKUST).
I am interested in cybersecurity, especially applications and implementations of cryptographic protocols, and like to play capture the flag (CTF) games. I previously played with and trained the academic team Firebird of HKUST and was one of the captains in 2020-2021. Currently, I am the coordinator of Open Innovation Lab (OIL) in CUHK, where I am responsible for the management, holding events, and giving CTF training as well. I also play CTF with the Black Bauhinia (blackb6a) CTF team based in Hong Kong.
