description An authentication method, comprising storing a unique value associated with a device (212) and a corresponding counter value (C) for the device (212), receiving a request for authentication of a target device (308), the request comprising a first tag authentication code (TAC) generated by the target device (308), the first tag authentication code generated using a unique value stored by the target device (308) and a changeable data part stored by the target device (308), locating the unique value and corresponding counter value (C) in the memory of the authentication server, using a cryptographic engine (352) to determine a second tag authentication code based at least in part on the unique value and the counter value (C) stored in the memory, comparing the first tag authentication code with the second tag authentication code to authenticate the target device (308), and updating the counter value (C) stored in the memory.
