Khoa Nguyen
I'm a Senior Lecturer at School of Computing and Information Technology (SCIT), University of Wollongong (UOW), Australia.
Before joining UOW, I was with Nanyang Technological University (NTU), Singapore, where I received my PhD in 2014, and worked as a Gopalakrishnan-NTU Presidential Postdoctoral Fellow and then as a Senior Research Fellow.
My research interests are in the areas of cryptography and information security. Currently, I'm particularly interested in the designs and analyses of privacy-preserving and/or quantum-safe cryptographic protocols.

Jan 2024: I recently joined the Steering Committee of ASIACRYPT as a representative of Viet Nam.
Dec 2023: A paper that revisits Stern's zero-knowledge framework and provides the first construction of (fully-dynamic) attribute-based signatures for circuits from codes was accepted to PKC 2024. Remarkably, the paper was rejected 10 times before finally being recognised.
