Presentation
I am Victor Dyseryn, currently Ph.D student in Applied Mathematics and Computer Science at the Research Center XLIM (UMR CNRS 7252) at the University of Limoges, France. I am being advised by Professor Philippe Gaborit and Professor Carlos Aguilar-Melchor.
My main interests are post-quantum cryptography and coding theory.

My Ph.D subject is Practical study of post-quantum algorithms based on error-correcting codes.
Post-quantum cryptography is the branch of cryptography which is resistant
against quantum attacks. Compared to currently used classical cryptography,
the underlying mathematical problems are different.
I work on a specific family of post-quantum algorithms based on rank metric
error-correcting codes. My objective is to find secure and
efficient (in size and time) crytosystems.
Together with my coauthors, we introduced a new rank-based key encapsulation mechanism (KEM)
without using ideal structures, improving in size all the existing unstructured post-quantum
lattice or code-based algorithms.
Keywords: Cryptography, Applied Mathematics, Coding Theory and Computer Science.
