摘要： An optical arrangement of at least a coherent light source (1), a strongly scattering object (5) (the PUF), and a pixe-lated photo-detector (6), wherein the pixels are comparable in size with the bright and dark patches of the speckle pattern produced by coherent radiation traversing the scattering object (5). Quantitively, the pixel size should be roughly λ/NA, where λ is the wave-length, and (i) NA=a/z for free-space geometry, with a being the beam radius and z being the distance between the exit surface of the PUF (5) and the pixelated detector (6), or (ii) NA is the numerical aperture of a lens (7) in an imaging geometry. In a preferred embodiment of the invention, there are tentative requirements that the pixels should be at least smaller than ηmaxλNA and preferably larger than ηmaxλ/NA, where (in an exemplary embodiment) ηmax=5 and ηmin=0.05, say. It will be understood by a person skilled in the art that the present invention is concerned with the optical arrangement of the PUF (5) and the photo-detector (6), rather than the photo -detector (6) per se.

摘要： The present invention relates to a device (100, 200, 300) and a method for creating challenge-response pairs. A basic idea of the present invention is to create a challenge in the form of light emitted onto a light scattering element (103, 203), which light will be scattered in the light scattering element and detected as a response to the challenge by light detecting elements (105, 205). The light scattering element comprises a transmissive material which contains randomly distributed light scattering particles (104, 204), which scatter incident light such that a random speckle pattern is created and spread over the light detecting elements. This random pattern is detected by the light detecting elements, and is known as the response to the challenge (i.e. the light) that was supplied to the light scattering element. Hence, a challenge-response pair is created. Further, picture elements (109, 209) are included in the device in order to enable modification of the challenge created by a light source (101, 201) and supplied to the light scattering element. By activating picture elements and thereby modifying the challenge, one will also modify the response that corresponds to the modified challenge.

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.

摘要： The present invention relates to a method and a device (104) for authenticating a plurality of physical tokens (101, 102, 103). A basic idea of the invention is to supply a sequence of interconnected devices (108, 109, 110), each device comprising a physical token (101, 102, 103), with a challenge of the respective physical token created during enrollment of said respective physical token, wherein the sequence of interconnected devices is arranged such that a data set supplied to the sequence is cryptographically processed with a response of a token comprised in a device and passed on to a token comprised in a subsequent device which further cryptographically processes the processed data set with its response until a response of a final physical token has been used to further cryptographically process the data set. Then, the data set which has been cryptographically processed with the responses of the tokens in the sequence is received and used together with the data set itself and data associated with the response of the respective token to authenticate the sequence of physical tokens.
