摘要： A distribution system and method for distributing digital information is provided, which has high recoverability from a security breach. The distribution system comprises a server (200) and a computing device (110). During an enrollment phase, the computing device obtains a first response from an integrated physically unclonable function (150) integrated in the computing device. The system comprises an enrollment module (130) for determining helper data from a decryption key and the first response to enable later reconstruction of the decryption key from the helper data and a second response obtained from the physically unclonable function. During a reconstruction phase, which occurs after the enrollment phase and typically after a security breach has occurred that revealed data and/or programming code of the computing device, the server may encrypt digital information using an encryption module (220) with a cryptographic encryption key corresponding to the decryption key. The computing device comprises a decryption module (120) for decrypting the encrypted digital information with the decryption key. The digital information may be used to send an update message to the computing device. Since, the decryption key need only be available at the computing device after the breach, it can recover even if data, such as a cryptographic key, or programming code of the computing device was revealed, and even if an attacker could eavesdrop on the encrypted digital information.

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.
摘要翻译： 作为挑战，光学标识符（1）可以用作用于产生斑点图案作为响应的物理不可克隆功能，作为响应。 该属性可以用于识别光学标识符或附加到其上的对象，用于信息载体的认证或用于生成交易密钥。 由于响应于给定挑战而获得的响应对于光学标识符，用于散斑图案的光束源和检测器的相对位置高度敏感，所以必须精确地调整该相对位置以可靠地获得对给定挑战的相同响应。 为此目的，提出一种具有用于将入射光束分成不同光束（6,7）的对准区域（3）的光学识别器，其可以被检测为检测器（8）上的对准信号（10a，10b，10c，10d） ）并用于监视和调整所述相对位置。

摘要： The present invention relates to a method and a system of securely computing a measure of similarity for at least two sets of data. A basic idea of the present invention is to securely compare two sets of encrypted data to determine whether the two sets of data resemble each other to a sufficient extent. If the measure of similarity complies with predetermined criteria, the two sets of data from which the encrypted sets of data originate are considered to be identical.

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.

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： The invention relates to an identification system, wherein the identifier is a body comprising an inhomogeneous material, which body is identified by subjecting it to mechanical vibrations, in particular acoustic vibrations, observing how the propagation of this mechanical vibrations is affected by inhomogeneities present in the body, and recognizing the body on the basis of a previous observation. Such an identifier body can be associated with an information carrier, allowing for the authentication of the information carrier, and for a conditional access or a copy protection scheme which can be relied upon. The acoustic identification according to the invention can be seen as an alternative to the optical identification of a body, which is known in the art, which alternative, compared to the optical identification, is characterized by higher robustness, various simplifications in the identification system and lower costs of implementation. The invention can also be applied for the generation of keys.

摘要： The present invention relates to a yoke ring for use in a deflection unit in a cathode ray tube (CRT). The yoke ring having a neck and a flared side, and being defined by an inner and an outer contour. According to the invention, the inner contour is periodically deformed in the radial direction, the contour having at least two local minima and maxima. This deformation influences the magnetic field generated by the coils in the CRT, leading to improved front-of-screen performance. In particular, astigmatism, coma and raster errors are reduced.
