Providing a Distance Bounding Protocol Named Pasargad in order to Defend against Relay Attacks on RFID-Based Electronic Voting System

The most important characteristic of RFID-based electronic voting system compared to traditional votingsystem is that votes in the electronic system are as contactless smart cards in place of paper ballots. Forcasting ballots, voters use a computer terminal to write their choices (their chosen candidates) intocontactless smart cards and then put the smart card inside the box. The most important threat forRFIDsystems is information robbery and relay attacks. In this article, by designing a protocol calledDistance Bounding Protocol it is tried to defend these systems against relay attacks.
