The Evolution of Pret a Voter

Опубликовано 28 июля 2016, 1:22

The challenge of making elections demonstrably accurate while guaranteeing ballot secrecy with minimal trust assumptions has been taken up by the crypto/security community. One of the approaches is the "Pret a Voter" concept, in which the vote is encoded by randomising the order of candidates. In this talk I will outline the Pret a Voter concept and describe its development over the roughly eight years since its inception. The design has evolved in the face of newly identified threats, advances in cryptographic primitives and demands for greater flexibility and efficiency. I will also outline the Pretty Good Democracy scheme and the incorporation of ideas from PGD in Pret a Voter, giving rise to Pret a Voter with Confirmation Codes.
