In the last few years, a lot of research effort has been made in the area of Radio Frequency Identification (RFID) technology. The widespread deployment of RFID tags and their increased usage in open environments brought on surface a need for supporting more advanced security features. Applying public-key cryptography constitutes an attractive solution and until now there are several proposed models. However, the RFID hardware introduces a number of limitations with respect to computational power and production cost and thus the feasibility of such attempts is always questionable. This paper, presents a survey in the area of public-key cryptography on the RFID systems and focuses on the GPS identification scheme, which was one of the first innovated proposals for low-resources hardware.
