ABSTRACT

E-voting systems are important tools for community participation in essential decisions of society. In comparison with traditional voting systems, e-voting systems have special advantages. Any evoting system is based on an e-voting protocol. In this paper, a new secure and efficient e-voting protocol is proposed based on ElGamal cryptosystem which provide all security requirements of a practical electronic voting. One of the new properties of proposed protocol is protection of voter's identity against Authorities and adversary by using implementable physical assumptions. In this protocol, each voter distributes his/her secret key among the election Authorities and finally eligible voters are recognition from their public key. Also due to having low communication volume, the proposed protocol is suitable for internet voting and communication networks with less bandwidth.
