Jiaxin Pan
Om
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).
Research Interests
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.
