Abstract (en)

[origin: WO2014060134A2] In order to check authentication using a physical unclonable function (6), an authenticator (3) comprises a PUF (6) and an authentication checking function (5). A challenge response pair (4A) comprising an item of challenge information (C) and an item of response information (R) is provided for the authenticator (3). The challenge information (C) is used as an input for the PUF (6) which generates a PUF response (PR) in response to the input of the challenge information (C). The PUF response (PR) and the response (R) are used for a comparison, wherein an enable signal (A) is provided on the basis of a result of the comparison.
