RFID System Security Analysis, Response Strategies and Research Directions

Radio Frequency Identification(RFID) system is a contactless automatic identification system using small, low-cost RFID tags. It enables recognition of the tag information via radio frequency communication, by attaching an RFID tag to an animate or inanimate object. Therefore, RFID system expected widely used in the object recognition and u-healthcare. The most important problem with an RFID system is that an adversary can access the tag information, which gives rise to privacy violation and forgery. In this respect, this paper defines the causes of the security threats occurring in RFID system and defines strategies to respond to the threats and related requirements. We review and analyze existing researches in order to present problems and propose research directions.
