Prabhanjan Ananth Amit Sahai
In this work, we propose a variant of functional encryption called projective arithmetic functional encryption (PAFE). Roughly speaking, our notion is like functional encryption for arithmetic circuits, but where secret keys...

We show how to construct indistinguishability obfuscation (iO) for circuits from any non-compact functional encryption (FE) scheme with sub-exponential security against unbounded collusions. We accomplish this by giving a...
