Abstract
A method of authenticating a target device using a reader and a data store comprising: sending a selected challenge data value from the reader to the target device multiple times; receiving at the reader the respective response data value generated by the target device in response to each instance of the challenge data value sent by the reader; determining a representative response data value from the response data values received by the reader; comparing the representative response data value against the response data values in the respective challenge-response data set; and determining that the target device is authentic if the representative data value matches any one of the response data values from a respective challenge-response data set.
