Abstract:
A method and system for identifying an authentication status of a first item. An RFID reader transmits zero and a random number to a first RFID tag associated with the first item. The first RFID tag uses a hashing function to compute a hash (H1) of a concatenation of an identifier (Id1) of the first RFID tag, the random number, and a first secret key and sends the hash H1 to the RFID reader which then transmits the identifier Id1 and the random number to a second RFID tag. The second RFID tag uses the hashing function to compute a hash (H2) of a concatenation of the identifier Id1, the random number, and a second secret key and sends the hash H2 to the RFID reader. The authentication status of authentic or counterfeit is determined for the first item based on whether or not H1 is equal to H2.
