Purpose – This paper aims to provide a solution for allowing an arbitrary number of weights andweight values to be used in an electronic voting system.Design/methodology/approach – Robust Electronic Voting System (REVS) was chosen, a votingsystem designed to support internet voting processes, as the start point for studying the introductionof vote weights.Findings – The work resulted in an internet voting system supporting vote weights, based on REVS.Research limitations/implications – In the solution presented, there is still a problem regardinganonymity, for the case of a single voter with a particular weighted vote. This is a fundamentalproblem, since it also exists in paper-based elections.Practical implications – This version of REVS has the same properties as the original REVS, apartfrom the anonymity issue above. Apart from this the process of registering voters got morecomplicated, since now it includes an extra action for binding a weight.Originality/value – To the best of the authors’ knowledge, this modified version of REVS is the firstelectronic voting system supporting vote weights. Another novelty of this work is the modulussharing optimization used for the RSA key pairs of each entity.
