All these principles were mandated as requirements, designed into, and successfully operated as features of, eVACS®, the electronic voting and counting system used since 2001 by the Australian Capital Territory Electoral Commission. How eVACS® achieves these requirements is described in this paper, with particular emphasis being given to security and transparency and the approaches adopted to ensure verifiability via electronic audit trails.enText/Conference Paper1617-5468
