Complete software defined RFID system using GNU radio
Aurelien Briand, Bruno Albert, Edmar Candeia Gurjão · 2012
In this paper we describe a complete Radio Frequency Identification (RFID) system, reader and tag, using the approach of software defined radio (SDR). We use the open source GNU Radio development toolkit to implement this SDR. The advantage of this approach is the possibility of to implement and test RFID applications using a flexible software platform. RFID readers in SDR have already been developed by others researchers, and our main contribution is the implementation of an RFID tag in accordance with EPC Gen2 RFID standard. The system is evaluated and it shown that it works with good performance, and as an example of application we implemented a cryptography protocol proposed to RFID.
