Label chip authentication system and method, label chip and storage medium

Abstract

The invention relates to a label chip authentication system and method, a label chip, computer equipment and a storage medium. To-be-encrypted authentication data is obtained through a tag chip; a secret key and safety configuration information which are sent by the reader-writer on the basis of an EPC protocol and generated on the basis of a national cryptographic algorithm are obtained; a presetrandom number is generated, the authentication data is encrpted according to a national cryptographic algorithm and the random number, the encrypted authentication data sent by the tag chip is obtained through a reader-writer, and the bidirectional authentication is carried out on the label chip based on an EPC protocol and the encrypted authentication data. Compared with a traditional password passing authentication mode, the authentication data is read and encrypted through the tag chip by utilizing the EPC protocol and the national cryptographic algorithm, and the encrypted authenticationdata is acquired through the reader-writer and is subjected to bidirectional authentication, so that the security authentication between the tag chip and the reader-writer can be realized, and the security of RFID tag authentication is improved.

Description

technical field [0001] The present application relates to the technical field of data security, in particular to an authentication system and method for a tag chip, a tag chip, computer equipment and a storage medium. Background technique [0002] With the development of communication technology, each communication device usually needs to interact with information in the process of interaction, and information transmission through RFID technology is one of the important ways. In the process of information transmission using RFID technology, Usually, RFID tags are used to store relevant data, and read or write through the reader. In this process, data transmission is usually involved, so the information exchange between the RFID tag and the reader is guaranteed. Security is very necessary. At present, the measures for protecting information security when reading and writing RFID tags are usually authenticated by passwords. However, authentication by passwords is easy to be br...

Problems solved by technology

[0002] With the development of communication technology, each communication device usually needs to interact with information in the process of interaction, and information transmission through RFID technology is one of the important ways. In the process of information transmission using RFID technology, Usually, RFID tags are used to store relevant data, and read or write through the reader. In this process, data transmission is usually involved, so the information exchange between the RFID tag and the reader is guaranteed. Security is very necessary. At present, the measures to protect information security when reading and writing RFID tags are usually authenticated through passwords. However, the way of authentication through passwords is easy to be broken by criminals.

[0003] Therefore, the traditional RFID tag authentication method has the defect of low security
