The organization and delivery of pervasive healthcare have benefited much from advances in wireless systems. While wireless systems and their components have certainly enhanced the quality of pervasive healthcare administered in remote locations, their potential in other areas of healthcare cannot be underestimated. We consider Radio Frequency Identification (RFID) tags, which are increasingly being...
Information visibility is of paramount importance for effective and efficient operation of supply chains. Although not the sole enabling technological source for information visibility in supply chains, RFID tags naturally allow for its seamless operationalization. RFID tags are notorious on issues related to security/privacy concerns, and these concerns are magnified in a supply chain context where...
Relay attacks occur when an adversary simply relays signals between honest reader and tag without modifying it in any way. Since the signal content is not modified by the adversary, none of the extant cryptographic protocols are immune to such attacks. There have been several proposed protocols that purport to alleviate this problem for a single tag. We propose a protocol that considers relay attacks...
