Secure RFID systems for supply chain applications
by Janice Warner
International Journal of Electronic Business (IJEB), Vol. 7, No. 1, 2009

Abstract: Radio Frequency Identification (RFID) is useful not only for tracking and identifying individual products but also for supply chain applications involving large shipment containers. Data associated with these containers clearly should be protected from unauthorised tracking, information interception through radio frequency eavesdropping, and physical compromise. Our solutions protect the data through encryption and a mutual authentication process between a secured tag and an authorised reader. Our unique design, which combines passive and active RFID circuitry, results in a secure active RFID tag that maintains battery life even in the presence of malicious probes designed to interrupt the supply chain.
