Problems solved by technology

But manufacturers are not satisfied, in order to store more user data, such as manufacturer name, manufacturer address, shelf life, loading date and other data, they increase the capacity of the label user storage area
But at the same time, it also brings hidden dangers to data security. Once the label is breached by malicious attackers, it is likely to lead to the loss and leakage of important product information.

Abstract

The invention provides an RFID tag feature code generation method and device based on a finite field traversal matrix. The device comprises a random matrix generation module, a ciphertext sequence calculation module, an abstract matrix generation module, a feature code generation module and a complex transformation judgment module. According to the invention, RFID data in each transportation stageand each storage stage of the supply chain system are collected; according to the technical scheme, a learning sample is established, and when the RFID tag feature code is established for the learning sample, the technical scheme that the traversal matrix is applied to the finite field is adopted, so that the robustness and the safety of the tag feature code are enhanced, and the tamper resistance of the RFID tag feature code is improved.

Description

technical field [0001] The present invention relates to the application field of RFID, in particular to a method and device for generating RFID tag feature codes based on a traversal matrix over a finite field Background technique [0002] Ergodic matrices are collections of column vectors based on finite fields. It is defined as: if yes just traverse then call A F q "Traversing the Matrix" on . Traversing matrices has been shown to have good divergence. [0003] RFID (Radio Frequency Identification Technology), as an easy-to-manipulate, simple, practical, and flexible application technology, has been widely used in transportation, equipment management, logistics management, food traceability and other fields. However, with the popularization and application and rapid development of RFID technology, the privacy and security issues involved are particularly prominent. Since the RFID tag feature code is too simple and not complex enough, under the conditions of wir...
