Lightweight RFID authentication protocol: An experimental study

The market for passive RFID tags has experienced significant growth in recent years. However, passive RFID tags suffer from having a limited physical memory space for strong cryptography. The rapid proliferation of the technology, combined with the technologypsilas physical limitations, encourages the development of a ldquolightweightrdquo authentication protocol. In this paper, a means to implement such an authentication protocol is presented. The protocol takes advantage of the password protected ldquokillrdquo function of a tag, to permit its alternative use as a simple password dialog. Experimental studies have been carried out to verify the effectiveness of the proposed approach, and promising results are obtained.
