On the Impossibility of Three-Move Blind Signature Schemes. Authors: Marc Fischlin · Dominique Schröder. Download: DOI: 10.1007/978-3-642-13190-5_10 (login may ...
Abstract. A seminal result in cryptography is that signature schemes can be constructed (in a black-box fashion) from any one-way function.
They provide a very general impossibility result that rules out a large class of three (or less than three) round blind signature schemes in the setting of both ...
We rule out black-box constructions of blind signature schemes from one-way functions. In fact, we rule out constructions even from a random permutation oracle.

Abstract. This paper concerns blind signature schemes. We focus on two moves constructions, which imply concurrent security. There are.
This paper presents an efficient blind signature scheme that allows a polynomial number of signatures to be securely issued while only three data exchanges are ...
