Analysis and Improvement of RFID Protocol Based on PUF
Wang Li-bin · Jisuanji gongcheng · 2011
This paper analyses a low-cost RFID protocol based on Physical Unclonable Function(PUF).The protocol cannot guarantee the claimed privacy and is not scalable.Concretely,any adversary is able to trace the same tag by replaying the protocol messages and its computational complexity and communication overhead of identifying a tag are both linear to the number of tags.Furthermore,a new PUF based RFID protocol is proposed which beats down the protocol from both security and efficiency.
