RFID technology application has made multi label collisions and security privacy issues increasingly prominent in logistics warehousing. A solution that combines RFID and chaotic encryption algorithm has been proposed and applied to anti-collision and security protocols for logistics warehousing labels to address these issues. Firstly, optimization analysis was conducted on the anti-collision of warehouse system labels using chaotic sequences. By comparing different types of labels, it was determined that the 6TypeB label has good anti-collision ability. On this basis, a bidirectional security authentication protocol based on a chaotic encryption algorithm for 6TypeB labels was studied. The data privacy and security of tags can be effectively protected by this protocol. Finally, a detailed analysis was conducted on the performance of 6TypeB logistics warehousing labels used. The 6TypeB system has an average label recognition rate of 73%, an average transmission efficiency of 95.31%, and an average memory usage rate of 93%. Meanwhile, the average stability of the bidirectional security authentication protocol based on the 6TypeB label system is 92.08%. By utilizing 6TypeB, data privacy and security of RFID can be significantly improved, leading to a new application direction for anti-collision and security of logistics warehousing labels.
