Weiqiang Wen's Homepage (original) (raw)

I am currently a Postdoc in the EMSEC team of the IRISA laboratory in Rennes,
working with Pierre-Alain Fouque and Adeline Roux-Langlois.

I have completed my PhD under the supervison of Prof. Damien Stehlé in LIP in ENS de Lyon
on hardness of difficult problems in lattices.

Research interests: Cryptography; Lattice-based problems
