Embodiment Construction

[0034] The embodiments and effects of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] Refer to attached figure 1 , the implementation steps of this embodiment will be further described in detail.

[0036] Step 1, the reader sends "hello" to the electronic tag as an inquiry message.

[0037] Step 2: After receiving the inquiry message, the electronic tag returns the old and new values ​​IDSnew and IDSold of the ID pseudonym stored in the electronic tag to the reader as a response message.

[0038] In step 3, the reader matches the old and new values ​​IDSnew and IDSold of the ID pseudonym of the received electronic tag with the old and new values ​​IDSnew and IDSold of the ID pseudonym of the electronic tag stored in the back-end database server.

[0039] The matching steps are as follows:

[0040] If the following two formulas are true, the matching is considered successful, indicating that the electron...

Abstract

The invention discloses a bidirectional identity authentication method for an ultra-lightweight RFID authentication protocol. The method is mainly characterized in that a back-end database server andan electronic tag respectively generate verification information by using exclusive-OR and cyclic shift operations, and mutual authentication is carried out between the electronic tag and a reader inthe ultra-light radio frequency identification RFID system. The method is specially designed for a resource-limited low-cost passive radio frequency identification (RFID) tag. The method is mainly characterized in that the method is safe and efficient, is easy to implement, can effectively resist common attacks in RFID authentication, such as a replay attack, a man-in-the-middle attack, a secret key leakage attack, a desynchronization attack and an anti-tracking attack, and is higher in safety.

Description

technical field [0001] The invention belongs to the technical field of information processing, and further relates to a two-way identity authentication method for ultra-light radio frequency identification RFID (radio frequency identification) in the technical field of information processing security. The invention can be used in a low-cost passive RFID system with limited resources to perform mutual authentication between an electronic tag and a reader in a radio frequency identification RFID system. Background technique [0002] In recent years, with the continuous development and progress of Internet of Things technology, the application of Internet technology has become more and more extensive. Radio Frequency Identification Technology RFID is a vital application technology in the Internet of Things technology. Radio frequency identification technology can realize automatic identification technology and can work normally in harsh environments. Due to cost constraints, ...
