Abstract

At Asiacrypt 2013, Qin and Liu showed a leakage-resilient chosen-ciphertext attacks (LR-CCA) secure public-key encryption (PKE) from one-time lossy filter (OT-LF) and hash proof system (HPS), from which, combining garbled circuits (GC), we present an LR-CCA secure generic construction for single-key and single-ciphertext functional encryption (FE) via hash proof system (HPS) and one-time lossy filter (OT-LF). We bypass known obstacles in realizing leakage-resilient using garbled circuits that make a non-black-box use of the underlying cryptographic primitives. Efficient instantiations of DDH-based and DCR-based HPS and OT-LF indicate that our approach is practical in realizing LR-CCA secure FE scheme under the standard assumptions. Moreover, our constructions from the DDH and DCR assumptions result in the same leakage rate as Qin and Liu’s.
