A design of authentication protocol for multi-key RFID tag

Abstract

RFID systems are spreading in the area of the industry and marketplace faster and now this time it is coming up to usual area covering individual life and environment as a core element of the ubiquitous technologies. But the RFID system has RF device communicates each other by radio frequency and it could make some serious problems on the important area such as privacy violation and information security. In this paper, we propose multi-keys RFID tag scheme including tag structure and authentication protocol which can support efficient security on the tag information by using SEED algorithm. The multi-key RFID tag could maintain multiple object IDs for different applications in a single tag and allow simultaneous access for their pair applications. The authentication protocol for multi-key RFID tag is designed to overcome the security and privacy problems and has enough robustness against the various attacks on the RFID system with low cost. We compared the security capability of the schemes and the evaluation results showed the proposed scheme has better efficiency than existing schemes. © Springer-Verlag Berlin Heidelberg 2007.
