Authentication and privacy are central issues for acceptance of any e-Voting system in particular and growth of e-Services in general. This paper aims to: (i) to analyze the appropriate architecture and propose new efficient architecture of electronic voting system in Kosovo, and (ii) to analyze the threat vectors and their avoidance in such system. The novelty of implemented solution is based on using dynamic queue list generated based on voters arrivals and identification at the polling station. The proposed architecture enables citizens to cast their vote in any polling station, in opposite to paper form voting where citizen is linked to his predefined polling station. The national election commission configures the smart card, as part of electronic voting infrastructure, to allow decryption of number of records that matches the number of voters in final country wide voting list. The communication between polling stations and central server is encrypted with server’s public key stored in digital certificate and every casted vote is digitally signed by ballot box private key. The developed model is used to compare the costs and efficiency of e-Voting against the traditional paper based voting system in Kosovo.
