An Improved Ownership Transfer and Mutual Authentication for Lightweight RFID Protocols

Radio Frequency Identification (RFID) technology is an automated identification technology which is widely used to identify and track all kind of objects. However, it is a challenging task to design an authentication protocol because of the limited resource of Lightweight RFID tags. Recently, a lightweight RFID authentication protocol and an ownership transfer of RFID tags are presented by Kulseng et al. Both protocols use Physically Unclonable Functions (PUF) and Linear Feedback Shift Registers (LFSR) which are well known lightweight operations. The number of gates which the protocols require can be significantly decreased and the most efficient protocol can be obtained with respect to the existing protocols. Unfortunately, their protocols face several serious security issues. In this paper, based PUF and LFSR, we suggest an improved mutual authentication and an improved ownership transfer for low-cost RFID Protocols. Security analysis shows that our protocol owns security and privacy.
