Enabling Trust and Privacy for RFID System

Future generation of RFID technology is moving towards integration with other systems. This new technology integration trend creates more benefits to user because potentially many problems could be solved in one integrated system. The integration of RFID with other systems is advantageous to users because it could use its unique contactless communication ability for numerous sectors of the community. Unfortunately, this special ability of RFID system is vulnerable because the tag can be tracked by adversary who then exploits and abuse data and location privacy. Past works on privacy-preserving RFID protocols have dealt with lots of issues regarding trust and availability. In this paper, we stress the importance of trust and privacy. We believe that data anonymity must be strengthened with integrity verification in every platform (machine or device) to avoid any untrusted platform from becoming threat to others. One such threat could be in the form of adversary making use of the privacy technique to hide its real identity. We believe that integrity verification which forms trust establishment for the system is crucial. Trust and privacy are usually contradictory in their mechanism, so we need to harmonize them to effectively protect user data. Therefore, we propose a hybrid technique for establishment of trust and privacy in RFID system. We also do trust and privacy analysis on our proposed model.
