Efficient Round Optimal Blind Signatures
Sanjam Garg and Divya Gupta
Abstract
Known constructions of blind signature schemes suffer from at least one of the following limitations: (1) rely on parties having access to a common reference string or a random oracle, (2) are not round-optimal, or (3) are prohibitively expensive.
In this work, we construct the \emph{first} blind-signature scheme that does not suffer from any of these limitations. In other words, besides being round optimal and having a standard model proof of security, our scheme is very efficient. Specifically, in our scheme, one signature is of size
