An RFID Mutual Authentication Protocol Based on Tag Grouping
Zhang Xue-ju
Abstract
Explore the tag grouping field less involved in current RFID security authentication protocol,Yoking Proof protocol's security problems are analyzed. An RFID M utual Authentication protocol based on Tag Grouping( M ATG) was proposed. The same tags are grouped by M ATG,reader can select a group of tags in the mutual authentication process,and then identify targets automatically in a protocol processing. Safety of the proposed protocol is analyzed and proved with the BAN logic,and then attack simulation is performed using C programming language. Theoretic analysis and simulation results show that M ATG protocol overcomes Yoking Proof protocol's shortcomings and improves working efficiency and safety when dealing with a group of tags.
