Lecture on "Structure-Preserving Signatures from Standard Assumptions, Revisited"
Date and Time: 2017-12-23 00:43:38

Speaker: Pan Jiaxin, Professor, Karlsruhe Institute of Technology

Date: Dec. 27, 2017

Time:2.30 p.m.—4.00 p.m.

Location: Room 1219, Block B, Zhixin Building, Central Campus

Sponsor: School of Mathematics, SDU


Abstract:

Structure-preserving signatures (SPS) are pairing-based signatures where all the messages, signatures and public keys are group elements, with numerous applications in public-key cryptography. We present new, simple and improved SPS constructions under standard assumptions via a conceptually different approach. Our constructions significantly narrow the gap between existing constructions from standard assumptions and optimal schemes in the generic group model


Bio:

Professor Pan got his Bachelor’s and Master’s degree in South China Normal University and his PhD in Ruhr-University Bochum of Germany, sponsored by a well-known cryptologist, Professor Eike Kiltz who was nominated as the winner of “Best Paper” of EUROCRYPT for four times. Currently he is devoted to postdoctoral research in Karlsruhe Institute of Technology, cooperating with his sponsor Professor Dennis Hofheinz who was nominated as the winner of “Best Paper” of EUROCRYPT for three times.


His main research direction is about provable security theory which refers to design and analysis of cryptosystem such as public key encryption, digital signature and identity-based encryption. Most of his achievements were published in high-level cryptographic conferences such as one of the three top-level conferences, CRYPTO, ASIACRYPT, and PKC. Therein, since 2014, he published papers in CRYPTO for four years in a row. He once visited some international prestigious research institute of cryptology for many times including ENS Paris, IDC, and NTT Tokyo.
