ABSTRACT
Radio-frequency identification (RFID) devices represent a promising new technology that, in the near future, could be applied in a wide range of applications. The increasing success presents a side effect due to the necessity to protect data stored in RFIDs guaranteeing security and privacy. This chapter presents, on one side, the motivations for addressing security and privacy in RFIDs and, on the other side, it analyzes different approaches proposed in the literature that aim at solving these issues. Such different approaches, based on asymmetric encryption, are described and compared by analyzing their properties and their applicability to RFID devices, taking into account their limitations in terms of computation performance and power consumption.
