The LAC cryptosystem that I co-designed has won the first prize of the post-quantum cryptography competition, hosted by Chinese Association for Cryptologic Research.
pqNTRUSign is a lattice based, same-key aggregatable signature scheme. After three years of revision, during which period, the scheme has been submitted to, and rejected by, NIST PQC standardization process, the pqNTRUSign paper is finally accepted for publication by Design, Codes and Cryptography. In this paper, we finally come up...

I just gave a talk at NIST’s second PQC Standardization Conference today on recent updates of the LAC cryptosystem that colleagues and I are working on. The slides can be found here and here.
This year’s Asiacript 2019 accepts
my paper with Shi Bai, Katharina Boudgoust, Dipayan Das, Adeline Roux-Langlois and Weiqiang Wen,
Middle-Product Learning with Rounding Problem and its Applications.
Here is the manuscript.
This is somewhat an extension of my last year’s Asiacrypt paper.
