An e-lottery scheme using Verifiable Random Function

Abstract

A number of e-lottery schemes have been proposed; however, none of them can satisfy all the identified requirements. In particular, some of them require a certain subset of players to remain online or the existence of a trusted third party (TTP) in order to generate the winning number(s) and some suffer from the forgery ticket attack. In this paper, we propose a new e-lottery scheme based on Verifiable Random Function that can satisfy all the identified requirements without the presence of TTP, yet the result of this generation is publicly verifiable. © Springer-Verlag Berlin Heidelberg 2005.
