A practical voting system for small-scale election

Voting is common in our daily life, from electing president to electing committee; we need to set up a complete electronic voting scheme suitable for all kinds of voting with safe guaranty where the voter´s privacy can be protected. However, most present electronic voting schemes are still in experimental stage. People often question about the security of electronic voting because all schemes require the verification of trusted centers. And these trusted centers add the complexity of processing. In this paper, we present a one-server private information retrieval (PIR) electronic voting scheme with secure coprocessor (SC). In the scheme, we not only protect personal privacy but also increase the security of the voting procedure. Besides, using only one server can lower the cost. This idea can be used in small-scale election practically, because of its high security, low cost and good efficiency. By this novel and practical electronic voting system, electronic voting can be applied more easily in everyday life.
