A novel lightweight PUF-based RFID mutual authentication protocol

Abstract

The widespread use of radio frequency identification (RFID) in IoTs makes authentication of RFID systems be widely concerned. In existing encryption schemes (e.g., Hash function) in electronic products, secure chip is hard to be used in high performance RFID system due to high computation complexity and cost. In this work, we consider problems in these performances and propose a PUF-GIMAP protocol by combining GIMAP protocol and physically unclonable functions (PUFs). The response of PUF is added into protocol. The mutual authentication between label and reader is realized by transmitting information such as secret key and dynamical pseudonym, which greatly ensures data security in transmission. After authentication, the reserved data is updated in time. The protocol analysis shows that the proposed scheme has the advantages of high security and high reliability.
