Aiming at solving the defects of security and privacy of conventional RFID authentication protocols and low authentication efficiency, this paper proposes a group tag security authentication protocol. In the group authentication protocol, it needs to prove that certain tags belong to the same group and exist at the same time. The applicability of RFID authentication protocol is introduced in low-cost tag applications, and an improved scalable lightweight RFID authentication protocol is proposed. The tags only generate pseudo-random numbers and perform join (||) and exclusive-OR (XOR) operations. The response message of the tag is identified by using an existing bit arbitration query tree based on grouping mechanism algorithm. Keeping update to the encrypted information in the tag is synchronized with the server throughout the group certification process. Based on these improvements, this protocol improves the efficiency and security of RFID system.
