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

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 t
