Distributed Fiat-Shamir Transform

ePrint Report: Distributed Fiat-Shamir Transform

Michele Battagliola, Andrea Flamini

The recent surge of distribute technologies caused an increasing interest towards threshold signature protocols, that peaked with the recent NIST First Call for Multi-Party Threshold Schemes.


Since its introduction, the Fiat-Shamir Transform has been the most popular way to design standard digital signature schemes.
In this work, we translate the Fiat-Shamir Transform into a multi-party setting, building a framework that seeks to be an alternative, easier, way to design threshold digital …
