Challenged-based tag authentication model |
摘要 |
A method of securing communications in an RFID system including a reader and an RF tag having a memory configured to store information comprises sending, from the reader, a message to the tag; the tag, in response to the message, generating a challenge value and sending the challenge value to the reader; in any order: the reader performing a mathematical operation on the challenge value based upon a key value to generate a challenge reply and sending the challenge reply to the tag and the tag independently computing a challenge response based on the key value and mathematical operation; the tag comparing the challenge response computed by the tag with the challenge reply sent by the reader; and the tag authenticating the reader if the challenge response matches the challenge reply. An RFID system including an RFID tag and a reader are configured to perform the above steps.
