Electronic vote scheme based on ring signature

Abstract

This paper proposes an electronic vote scheme generated by the ring signature with divised private key. The algorithm respects the basic requirements regarding the voting process. The fact that it comes from a ring signature confers a strong anonymity to the developed scheme. The mathematical structure where the work in done is the remainder classes modulo n ring. There are presented two variants, the first one refers to the situation when all voting entities are registered before the voting process and the second one offers the possibility to vote other entities, entities who weren't registered before, too. The security from the cryptographic view is also analized.
