The Evolution of RFID Security and Privacy: A Research Survey

This paper presents the recent technical research on the problems of privacy and security for radio frequency identification (RFID). RFID technology is already used widely and is increasingly becoming a part of daily life. However, issues regarding security and privacy with respect to RFID technology have not been resolved satisfactorily. There are huge number of challenges, which must be overcome to resolve RFID security and privacy issues. It is because of the many constraints attached to the provision of security and privacy in RFID systems. These challenges are chiefly technical and economic in nature but also include ethical and social issues. Along with meeting the security and privacy needs of RFID technology, solutions must be inexpensive, practical, reliable, scalable, flexible, inter-organizational, and long lasting. This paper reviews the approaches which had been proposed by scientists for privacy protection and integrity assurance in RFID systems, and treats the social and technical context of their work. This paper can be useful as a reference for non specialist, as well as for specialist readers.
