Lightweight RFID group label authentication method based on cloud database

Abstract

The invention provides a lightweight RFID group label authentication method based on a cloud database, aiming at solving the technical problem that a shared key of the cloud database and a group label to be authenticated has update desynchronization and increasing the efficiency and accuracy of authentication at the same time. The method comprises the following implementation steps: (1) a reader broadcasts an authentication request to a group label to be authenticated; (2) the group label to be authenticated gives a response, and the reader forwards the response to the cloud database; (3) the cloud database verifies the identities of the reader and the group label to be authenticated; (4) the cloud database eliminates illegal invalid labels and sends the legal label information to the group label to be authenticated; (5) the group label to be authenticated authenticates the cloud database; (6), the group label to be authenticated eliminates the illegal invalid labels; (7) the cloud database updates the shared key; and (8) the authenticated group label updates the shared key and verifies a key authentication message. According to the lightweight RFID group label authentication method provided by the invention, the two-way authentication between the cloud database and the group label to be authenticated can be realized, and high safety can be achieved.

Description

Technical field [0001] The invention belongs to the field of communication technology, and relates to a lightweight RFID group tag authentication method, in particular to a lightweight RFID group tag authentication method based on a cloud database, which can be used in an RFID system with low-cost requirements. Background technique [0002] Radio Frequency Identification (RFID) technology refers to radio frequency identification, a non-contact automatic identification technology, which is mainly used in logistics management, access control systems, automatic toll collection of roads and bridges, and library book classification and management And so on. The traditional RFID system mainly includes three parts: electronic tag, reader and back-end server. [0003] The back-end server and reader of the traditional RFID authentication scheme are connected by a wired channel. Although this connection method improves system security, the working capacity of the back-end database is small....
