The invention discloses a method for mobile RFID authentication. The method includes the following steps: a tag and a reader-writer authenticate each other according to signals sent by each other, and send authentication messages to a background database after authentication; the background database determines whether the reader-writer and the tag are both true; if the reader-writer and the tag are both true, the background database updates a shared key to get a new shared key, and sends the new shared key to the reader-writer; if the reader-writer determines that the background database is true, the reader-writer updates the new shared key, and sends the new shared key to the tag; and if the tag determines that the background database is true, the tag updates the new shared key. A secure mobile RFID system two-way authentication scheme is designed in the method, which improves the security of the system and protects the privacy of users. The invention further discloses a system for mobile RFID authentication which has the same advantage.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a mobile RFID authentication method and system. Background technique [0002] RFID (Radio Frequency Identification, also known as radio frequency identification) technology is a communication technology that can identify specific targets through radio signals and read and write related data without establishing mechanical or optical contact between the identification system and specific targets. The RFID system generally consists of three parts: background database, tags and readers. [0003] In the early days of RFID technology, there was a wired connection between the reader and the back-end database, so it was considered a secure communication. However, with the rapid development of science and technology, the close integration of the Internet of Things and wireless communications, and the rapid development of mobile payment and other services, mobile RFID systems have...
