Bar-Ilan Winter School on Lattice-Based Cryptography Feb 19-22 2012.
This is what I sthink about studying in Aarhus.
My research in a nutshell.
VIFF - Orlandi Runtime.
Implementation of Secure Database Intersection.

About me:

My main area of research is Secure Multi Party Computation, both practical and theoretical aspects.

My Erdős number is 3: P. Erdős - C. Pomerance - I. Damgård - Me; unfortunately, my Bacon number is still undefined. Other numbers can be found here and here.
