Verifiable Random Functions NIWI Functional Encryption
2017/2/20
Recently, Bitansky [Bit17] and Goyal et.al [GHKW17] gave generic constructions of selec- tively secure verifiable random functions(VRFs) from non-interactive witness indistinguishable proofs (NIWI) an...
Efficient non-interactive zero-knowledge proofs are a powerful tool for solving many cryptographic
problems. We apply the recent Groth-Sahai (GS) proof system for pairing product equations (Eurocrypt...
