Background and activities
Jiaxin Pan is an associate professor (førsteamanuensis) at the Department of Mathematical Sciences. He bleongs to the Algebra Group. He obtained his PhD from Ruhr-Universität Bochum (Germany) and after that he was a postdoc at Karlsruhe Institute of Technology (Germany).
Pan is interested in (public-key) cryptography, in particular, cryptographic systems with mathematically sound proofs. More specifically, he is interested in:
- Identity-based encryption schemes
- (Non-interactive) zero-knowledge proof systems
- (Structure-preserving) signature schemes
- Tight security reductions
- More general topics (in cryptography) that he is fascinated by
Most of his work are published at top-tier journals and conferences (such as Journal of Cryptology, Crypto, Eurocrypt, Asiacrypt, etc.). Please visit his DBLP for a more up-to-date list of his publications.
- 2022 – 2026: NTNU Outstanding Academic Fellows Programme (Career development award)
- 2021 – 2025: Principal investigator of a Young Research Talent project, Reserch Council of Norway, under the topic ground-breaking research (FRIPRO)
- 2021 – 2023: Principal investigator (jointly with Sanjam Garg from UC Berkeley) of a Peder Sather Grant
It is my great honor to serve as a PC member of the following flagship and renowned international conferences:
- IACR Eurocrypt: 2023
- IACR Asiacrypt: 2019, 2020, 2021
- IACR PKC: 2022
- CT-RSA: 2020, 2021
- ESORICS: 2021, 2022
Recent Publications at Peer-Reviewed Conference Proceedings and Journals
My research is regularly published at the flagship IACR conferences (such as ASIACRYPT, CRYPTO, and EUROCRYPT) and the major area IACR conference (PKC). One of them was invited and published in the prestigious journal, Journal of Cryptology.
