Method for Processing Security between RF Writer and Reader

摘要

A security processing method between an RF writer (Writer) and an RF reader (Reader) provided in each device, the method comprising the steps of: The encryption key is generated by substituting the serial number stored in the tag into the designated key generation algorithm, and the program of the RF writer side apparatus encrypts the code value to be written into the RF tag through the generated encryption key, Writer writes the RFID tag-to-reader communication parameter value and the encrypted code value in the RF tag, and the program of the RF reader-side apparatus generates a key generation algorithm corresponding to the key generation algorithm of the RF writer When the program of the RF reader side device reads the code information from the RF tag, the serial number provided in the RF tag is read out The program of the RF reader device confirms the encrypted code value included in the read code information, substitutes the serial number into the key generation algorithm, and decrypts the encrypted code value using the decryption key generated do.
