Abstract

Despite the massive improvements in technology the goal of having accurate, anonymous and voter-verifiable elections has not yet been realized. The existing electronic voting schemes that provide secret voter-verifiable receipts are based on ''classical'' mix-nets. These mix-nets approaches do not scale well and are designed to provide a fixed degree of anonymity which cannot be increased by the voters who do not trust the system. In this paper we propose a new voting scheme that allows the voters to increase their degree of anonymity beyond the one implicitly provided by the system and provides secret voter-verifiable receipts. The proposed scheme utilizes incoercible, voter-verifiable receipts. The scheme is robust as no reasonable-sized coalition can interfere with the correct operation. The scheme has low communication complexity and thus it is efficient to use in large scale elections.
