Attacks on RFID-Based Electronic Voting Systems

Many secure systems, such as contactless credit cards and secure entrance systems are built with contactless smartcard RFID technologies. In many cases these systems are claimed to be secure based on the assumption that readers and tags need to be in close proximity (About 5cm) in order to communicate. However, it is known that this proximity assumption is false: Relay attacks are a class of hardware-based attacks which compromise the safety of such systems by dramatically extending the interrogation range of the contactless system. Interestingly, the proposed Israeli e-voting scheme is based on contactless smartcards.
