A global approach for the improvement of UHF RFID safety and security

Abstract

Radio Frequency Identification (RFID) devices are widely used in many domains such as tracking, marking and management of goods, smart houses (IoT), supply chains, etc. However, there is a big number of challenges which must still be overcome to ensure RFID security and privacy. In addition, due to the low cost and low consumption power of UHF RFID tags, communications between tags and readers are not robust. In this paper, we present our approach to evaluate at the same time the security and the safety of UHF RFID systems in order to improve them. First, this approach allows validating UHF RFID systems by simulation of the system behavior in presence of faults in a real environment. Secondly, evaluating the system robustness and the security of the used protocols, this approach will enable us to propose the development of new more reliable and secure protocols. Finally, it leads us to develop and validate new low cost and secure tag hardware architectures.
