Abstract:
A central concept in secure computation is that of correlated random variables (or correlations). In this talk, I will go over correlations, connections to cryptography, useful algebraic structures, and finally some applications.

Specifically, I will describe a new class of correlations over groups called ‘Zero alternating sum’ and show how it allows secure 2-party computation over groups.
