Speaker: Vyacheslav Futorny, SUSTech International Center for Mathematics, Shenzhen, Guangdong, China
Time: 2:00pm–3:00pm
Place: CMC 130
Sponsor: M. Elhamdadi

Abstract

We will discuss the state of the art of the theory of differential operators on algebraic varieties. In particular, the Noncommutative Noether's problem for the Weyl algebra will be considered.

Title: Cryptography based on supersingular isogenies
Speaker: Kirsten Eisenträger, Penn State University
Time: 3:00pm–4:00pm
Place: CMC 147
Sponsor: J. Biasse

Abstract

Cryptosystems based on supersingular isogenies are one viable option for use in post-quantum cryptography. These systems rely on the hardness of computing isogenies between elliptic curves. In this talk we discuss the graph theoretic interpretation of this problem and also the equivalent problem of computing endomorphism rings. We give some advantages and disadvantages for using these systems for cryptography and examine how secure they are.
