Two-way authentication method based on simple logic encryption and time stamp

Abstract

The invention discloses a dual authentication method based on simple logic security and timestamp, and mainly solves the problem that an existing RFID (Radio Frequency Identification) system is bad in safety performance. The method comprises the following steps: 1, generating a random timestamp TR and transmitting a session initiation request to a label by a reader of an RFID network; 2, comparing the TR with a timestamp Tt stored by the label by the label to generate and transmit displacement authentication information value to a reader; 3, transmitting the received information value to a server by the reader; 4, verifying a label identity by the server, and terminating the session according to a verification result or transmitting the returned authentication information value to the reader through authentication information value; 5, transmitting the information value received by the reader to the label; 6, verifying the identity of a rear-end server to confirm whether the label is authenticated. The method provided by the invention has the advantages of high safety and high execution efficiency, and can be applied to an RFID application field with high safety requirement and low cost.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a radio frequency identification two-way authentication method, which can be used for the transmission of digital information. Background technique [0002] Radio Frequency Identification (RFID), as a fast, real-time, accurate collection and processing of high-tech information, has been listed as one of the ten most important technologies in the 21st century. Since RFID has the advantages of non-contact, batch and remote reading, long service life, and convenient and quick operation, it has been widely used in many fields such as production, retail, logistics, and transportation. In addition, in the foreseeable future, RFID will become more portable and efficient, and its cost will be further reduced. At that time, its application fields will become more extensive. [0003] However, since the tags and readers communicate through radio frequency signals, this open wireless ...

Problems solved by technology

Although such protocols are simple in operation and high in execution efficiency, the security performance of these protocols is relatively low, and they have not completely solved the deficiencies in resisting tracking, anti-counterfeiting, anti-replay, and preventing security attacks, and these simple operations are often accompanied by Potential Security Vulnerabilities
