# Discovering mathematics and its applications

The ULB mathematics colloquium aims to bring talks on all areas of mathematics to a broad audience (from Masters students up).

* Current trends and challenges in post-quantum cryptography*

If large enough quantum computers can be built then they will factor integers and solve elliptic curve discrete logarithms, and therefore break most public key cryptosystems in current use. In response, a whole new field of post-quantum cryptography (cryptosystems that can be implemented on classical computers but are secure against an attacker with a quantum computer) has been initiated and is rapidly growing. I will survey some of the main trends in post-quantum crypto, focussing primarily on systems based on isogenies and lattices, and present a number of challenges and open problems.

The talk will take place in the Salle des Profs at 16:30. Coffee, tea and biscuits will be served in the foyer by the Salle des Profs, from 16:00. The Salle des Profs is on the 9th floor of building NO, of the Campus de la Plaine. Maps of the campus and directions are available here.
