Embodiment Construction

[0025] refer to Figure 1~4 . This example is for an actual mobile RFID system. The specific process of the method of the present invention will be described in detail below. The specific process is divided into three stages: registration stage, normal authentication stage and fast authentication stage. Follow the steps below to implement:

[0026] Symbolic descriptions of variables and operations in the examples.

[0027]

[0028] (1) Registration stage.

[0029] The tag T and the mobile reader R must be registered on the server S first, and the mobile reader R can authenticate the tag T only after the registration is successful. The method of the invention can enable the mobile reader to only identify specific labels through the authorization of the server. For example, in the method of the present invention, if the shared key of the labels of the A-type products is all X, and the shared key of the labels of the B-type products is Y. In this way, if the server sets...

Abstract

The invention discloses a low-cost tag based mobile radio frequency identification authentication method which is used for solving the technical problem that existing mobile radio frequency identification authentication methods are low in efficiency. According to the technical scheme, mobile radio frequency identification authentication is divided into three stages of registration, normal authentication and rapid authentication, information interaction times are decreased, interactive processes between a server, a mobile reader and a tag are simplified, and mutual authentication between the mobile reader and the tag as well as between the mobile reader and the background server is achieved. Requirement on rapid completion when the same tag needs to be read for multiple times in actual demand is met, authentication efficiency is improved, and system safety is guaranteed.

Description

technical field [0001] The invention relates to a mobile radio frequency identification authentication method, in particular to a low-cost label-based mobile radio frequency identification authentication method. Background technique [0002] In the mobile radio frequency identification (radio frequency identification, hereinafter referred to as RFID) system, the tags and mobile readers, the mobile reader and the server are all connected wirelessly, the reader is no longer a trusted entity, and the reading and writing range of the mobile reader is not Restricted, the mobile reader can collect tag information indefinitely, which is more likely to expose the privacy of the mobile reader owner. This makes the mobile RFID system face a more complex wireless communication environment than the traditional RFID system, and is more vulnerable to security threats such as eavesdropping, counterfeiting, and replay. Therefore, it is necessary to design a new security authentication meth...
