Studying privacy in electronic voting protocols and comparing its methods of provision
In the present paper first by introducing the inherent requirements of electronic voting and comparing them with the ones provided by researchers until the present time, a formal definition of privacy in electronic voting was given. Then by taking into consideration the privacy, developments in providing electronic voting protocols were investigated. Then results of the investigations were given and the methods of providing privacy in the protocols were introduced. In the end these methods were examined and compared and the homomorphic encryption was proposed as the best method.
