Document Type and Number:
WIPO Patent Application WO/2020/215679
Kind Code:
A1
Abstract:
Disclosed is a system for encrypted communication between an RFID tag and a reader-writer. The system for encrypted communication between the RFID tag and the reader-writer comprises an RFID tag, a reader-writer comprising a first encryption module and a second encryption module, and a decryption module, wherein an encryption algorithm unit is provided in the RFID tag, and when the encryption algorithm unit communicates with the reader-writer, bidirectional identity authentication can be performed with the first encryption module by means of the reader-writer while encryption and decryption of communication data of the RFID tag and the reader-writer are completed; the first encryption module transmits the decrypted RFID tag information read by the reader-writer to the second encryption module; the second encryption module reprocesses and encrypts the read data and transmits the data to the decryption module; the decryption module decrypts the data encrypted by the second encryption module and transmits the decrypted data to an application system for use. The present invention has the beneficial effect that when the RFID tag communicates with the reader-writer, encrypted communication can be performed, and thus, the security is high.
