An adaptive secure RFID scheme supporting multiple databases

In recent years, the research on Radio Frequency Identification (RFID) system has presented certain solutions that can meet the corresponding security requirements to some extents. However, the issues with multiple databases in RFID system, which are common in the real world, have gained little attention in the existing schemes. Although ONS (Object Name Service) solution is aimed at supporting multi-database in RFID system, it still has great security risk because of the lack of protection of the tag ID. In this paper, a new solution is presented which can provide sound protection of the tag ID and is adaptable to multiple databases, which can meet the security requirements of RFID system.
