Hashing Garbled Circuits for Free
ADVANCES IN CRYPTOLOGY - EUROCRYPT 2017, PT III, pp. 456-485, 2017.
We introduce Free Hash, a new approach to generating Garbled Circuit (GC) hash at no extra cost during GC generation. This is in contrast with state-of-the-art approaches, which hash GCs at computational cost of up to 6x of GC generation. GC hashing is at the core of the cut-and-choose technique of GC-based secure function evaluation (SFE...More
