A security framework in RFID multi-domain system

previous approaches, it's generally assumed that all Radio Frequency Identification (RFID) tags belong to a single RFID domain system (we name this as RFID single domain system). To date, most researches in the RFID single domain system have been on authentication protocols against a variety of attacks. This paper considers the security and privacy problems regarding that RFID tags used by different two or more RFID domains (we name this as RFID multi-domain system). We divided the security and privacy mechanisms in RFID multi-domain system into 3 conceptual parts: RFID forehand system security, RFID backend system security, and RFID inter-domain system security. First, we review RFID forehand and backend system security issues. Second, we present a security framework in RFID multi-domain system. Third, we propose and evaluate authentication and authorization for RFID inter-domain system with a case study.
