Batch Groth-Sahai
Abstract. In 2008, Groth and Sahai proposed a general methodology for constructing non-interactive zeroknowledge (and witness-indistinguishable) proofs in bilinear groups. While av...

Fair Blind Signatures without Random Oracles
A fair blind signature is a blind signature with revocable anonymity and unlinkability, i.e., an authority can link an issuing session to the resulting signature and trace a signat...

Compact E-Cash and Simulatable VRFs Revisited
Abstract. 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...

A Domain Transformation for Structure-Preserving Signatures on Group Elements
We present a generic transformation that allows us to use a large class of pairing-based signatures to construct schemes for signing group elements in a structure preserving way. A...
