In this talk, we will present the notion of functional encryption and recent progress in the area. We will begin by describing the concept and origins of functional encryption. Next, we will describe intuitively why current bilinear map based constructions appear to be “stuck” with boolean formula type functionality even in the public index setting. Finally, we will see some very recent work that uses multilinear forms to move beyond these barriers and achieve functionality for any circuit.
