Abstract: RFID is now a widespread method used for identifying people and objects. But, not all communication protocols can provide the same rigorous confidentiality to RFID technology. In return, unsafe protocols put individuals and organizations into jeopardy. In this paper, a scheme that uses multiple low cost tags for identifying a single object is studied. Through algebraic analysis on chronologically ordered messages, the proposed multi tag arrangement is shown to fail to provide the claimed security. The weaknesses are discussed and previously proven precautions are recommended to increase the security of the protocol, and thus the safety of its users.
