Book excerpt: RFID tags are more and more used for critical applications within harsh environments (aeronautics, railways) or for secure applications such as identification, countermeasure against counterfeiting. However, such low cost systems, initially designed for non-critical applications with a high volume, are not robust by themselves. For critical applications, a malfunction of RFID chip may have serious consequences or induce a severe security breach for hackers. Dysfunctions can have many origins: for instance, hardware issues can be due to aging effects or can also be due to hackers attack such as optical or electromagnetic fault injection. It is thus a common practice for critical applications to increase the robustness of RFID system. The main purpose of this PhD Thesis is to increase UHF tags robustness by proposing new digital architectures of RFID chips which would be resilient against both hardware attacks and natural defects.Usual design techniques for robustness IC improvement consist in evaluating the design robustness by simulation and to do this independently of the design validation. The main technique for robustness evaluation is the simulation based faults injection. Within the RFID context such an approach only based on simulation has several drawbacks. In fact, simulations often are inaccurate because the system behavior relies on several parameters such as the global electromagnetic environment, the number of tags present in the reader field, the RFID protocol parameters.The purposes of this PhD are to develop a design method dedicated to RFID system based on hardware prototyping in order to avoid time consuming simulations and then to evaluate the design within a real environment.The hardware prototyping based on FPGA allows the design to be validated in a real environment. Moreover, using instrumentation techniques for fault injection within FPGA , it will be then possible to analyze the effects of faulty tags on the global system in terms of safety and security and then to propose countermeasures.In this thesis an FPGA based emulation platform called RFIM has been developed. This platform is compliant to EPC C1 Gen2 RFID standard. The RFID tag emulator has been validated functionally in a real environment. The RFIM platform uses the instrumentation technique for injecting faults in the digital tag circuit. Through fault injection campaigns RFIM platform can analyze the effect on the entire system of the faults injected into the tag, and ten validate new robust digital architectures.The RFIM platform has been used to demonstrate the effects of further attacks against RFID systems based on the insertion of faulty or malicious tag that contains a hardware Trojan. Finally, RFIM platform helps to develop countermeasures against the fault effects. These countermeasures have been implemented and tested in a real RFID environment with several tags and reader.
