A Protocolized, Comparative Study of Helios Voting and Scytl/iVote

E-voting implantation is happening at a slower pace than anticipated. A plethora of technical and social challenges hinder a deeper implementation. In this article, the problem is addressed by applying a practical evaluation framework to two of the most relevant e-voting tools: Helios Voting and iVote from Scytl. The framework is strongly based on the technical requirements issued by the Council of Europe in 2017. The authors believe it can constitute a useful source of information for election officials, researchers and even voters. The final purpose is contributing to a gradual, secure and protocolized expansion of e-voting in Europe; more so in the present times, with mounting geo-political challenges and tensions.
