Spectacular expansion of RFID systems and applications by several industries such as business, electronics, health, marketing, transportation, etc. has made RFID ever more popular. Within this context, the industry search for lower tag weight and low cost system together with solemn security to satisfy the consumer. Tag search is among the most requested protocols in such systems. Being light weight...
Several grouping proof protocols for RFID systems have been proposed over the years but they are either found to be vulnerable to certain attacks or do not comply with the EPC class-1 gen-2 (C1G2) standard because they use hash functions or other complex encryption schemes. Among other requirements, synchronization of keys, simultaneity, dependence, detecting illegitimate tags, eliminating unwanted...
Near Field Communication (NFC) provides means to close-range contactless identification and communication for mobile phones and other devices alike. NFC is a new technology but it is maturing fast as it is being standardized. The first NFC services have mostly been simple applications but with the expansion of NFC technology and its application areas there is an urgent need to move from stand-alone...
Radio Frequency Universal Smart Cards (RF-UCard) open up the possibility for various attacks violating user privacy. In this paper, we propose a strong and lightweight role-based mutual authentication protocol. By employing the mutual authentication and the reader-role validation, the protocol can effectively defend against both passive and active attacks, including the invalid data access from the...
