In recent years, radio frequency identification technology has moved into themainstream applications that help to speed up handling of manufactured goodsand materials. RFID tags are divided into two classes: active and passive.Active tag requires a power source that's why its cost is more than passivetags. However, the low-cost RFID tags are facing new challenges to security andprivacy. Some solutions utilize expensive cryptographic primitives such as hashor encryption functions, and some lightweight approaches have been reported tobe not secure. This paper describes a lightweight Mutual authentication and ownershiptransfer protocol utilizing minimalistic cryptography using PhysicallyUnclonable Functions (PUF) and Linear Feedback Shift Registers (LFSR). PUFs andLFSRs are very efficient in hardware and particularly suitable for the low-costRFID tags. To functioning security in low cost RFID tag minimum gaterequirement is 2000 gates. To implement security protocols using PUF and LFSRfunctions need only approx 800 gates. In this paper it is explained how we canauthenticate and transfer ownership of low cost RFID tag securely using LFSRand PUF as compared to existing solutions based on hash functions.
