Abstract： |
An encrypted validation method of radio-frequency distinguish system, belongs to radio-frequency communication field. The method is: the card reader awake the label the card reader get the information of code-key, and the computer create the code-key the card reader send the random number RA and the data-wrap RA¡¯ and RB to the label the random number RA is encrypted by the label and get RA¡¯¡¯ if RA¡¯=RA¡±, the card reader pass the validation the label encrypt the random number RB by using the encrypted arithmetic and the code-key to get RB¡¯ the label return RB¡¯ to the validated card reader the card reader encrypt the random number RB to get RB¡¯¡¯, if RB¡¯=RB¡±, the label passes the validation the validated label and the card reader can make the following communication normally each other. The invention do not create additional burden of the system database, and easy to be established in RFID system which base on any RFID communicative consultation. |
