Security Protocol for Low-cost RFID System Based on PUF
Yan Da-sun · Jisuanji gongcheng · 2010
This paper analyses the security problems existed in low-cost RFID system,and presents a security protocol based on PUF.The protocol uses Physically Unclonable Functions(PUF) to identify the tag,and uses the Linear Feedback Shift Register(LFSR) to generate random series,encryptions the communication between the reader and tag,so it can resist replay attack,tracking attack,physical attack,eavesdropping attack and other attacks.Using the FPGA,PUF and LFSR are implied on the Altera DE2 board.The FPGA is programmed through Quartus II 8.0.Experimental result shows that the presented protocol meets the requirement on processing time and the number of gates on low-cost tags.
