摘要： The present invention relates to a method of authenticating, at a verifier (210), a device (101, 201) comprising a physical token (102), a system for performing authentication and a device comprising a physical token which provides measurable parameters. A basic idea of the present invention is to provide a secure authentication protocol in which a low-power device (101, 201), for example an RFID tag, comprising a physical token (102) in the form of a physical uncloneable function (PUF) is relieved from performing cryptographic operations or other demanding operations in terms of processing power. To this end, a PUF device (101, 201) to be authenticated verifies if it in fact is being queried by an authorized verifier. For instance, an RFID tag comprising a PUF (102) may be arranged in a banknote which a bank wishes to authenticate. This verification is based on the bank's unique ability to reveal concealed data, such as data having been created in an enrolment phase at which the RFID tag (or actually the PUF) was registered with the bank. Now, the RFID tag again challenges its PUF to create response data sent to the verifier. The verifier checks whether the response data is correct and, if so, authenticates the device comprising the physical token, since the device is able to produce response data that corresponds to response data concealed and stored in the enrolment phase.

摘要： An optical identifier (1) can be used as a Physical Unclonable Function for producing a speckle pattern, as a response, upon being challenged with a light beam, as a challenge. This property can be used for identification of the optical identifier or of an object attached thereto, for the authentication of an information carrier or for generation of transaction keys. Since the response obtained in response to given challenge is highly sensitive to the relative position of the optical identifier, light beam source and detector for the speckle pattern, this relative position has to be accurately adjusted to reliably obtain the same response to a given challenge. To this aim, an optical identifier is proposed having an alignment area (3) for splitting an incident beam into distinct beams (6, 7) which can be detected as alignment signals (10a, 10b, 10c, 10d) on a detector (8) and used for the monitoring and for the adjustment of said relative position.
