Abstract: Aiming at the problems in the key generation algorithm of existing radio frequency identification systems, such as the leakage of tag identity information, the security of key forgery attacks, the high cost of label calculation, and the lack of algorithm theory proof process, this paper designs the wireless key generation algorithm of RFID system that is applicable to anti-tag privacy leakage in three common scenarios. By giving the algorithm a complete GNY model, hypothetical model and security model, the rationality and feasibility of the algorithm are proved. Finally, the analysis of algorithm security and tag cost between related algorithms shows that the new algorithm has higher security and lower cost.
