摘要： It is described a RFID device (231a, 231b, 231c, 331) comprising a data memory (236) and an electronic circuit arrangement (237, 238, 239, 247) coupled thereto. The electronic circuit arrangement has a first and a second operational configuration, wherein by receiving a control command (250a) the electronic circuit arrangement can be switched irreversibly from the first to the second configuration. The RFID device further comprises a communication interface (245) being coupled to the electronic circuit arrangement. In the first configuration the RFID device is adapted to communicate with a standard RFID reader (110) via the communication interface. In the second configuration the communication with the standard RFID reader is disabled and the RFID device is adapted to communicate with a readout-RFID device (370). The RFID device may be equipped with a secondary communication interface that can be used to communicate with the RFID device in a privacy- preserving manner. After the RFID device has been disabled, the secondary interface can be used to access data in a secure manner.

摘要： The present invention relates to an electronic device (102), comprising a physical uncloneable function (PUF) module, and circuitry (108) adapted to receive a cryptographic query (α) from an electronic unit (104), read, from the PUF module, data generated at a challenge of the PUF module, and generate a cryptographic response (β) based on the data, a random noise component comprised in the data, and the cryptographic query (α), thereby enabling authentication of the electronic device (102). An advantage with the invention is that it will not be necessary to include an additional random generator together with the electronic device (102), as the fuzzy output provided by the PUF module can be seen as already containing a random noise component. In some cryptographic schemes, the random noise provides for a possibility to reach a higher level of security and to minimize the possibility for a third party to find patterns in cryptographic responses generated during use of the electronic device (102). The present invention also relates to a similar authentication method.
摘要翻译：本发明涉及一种电子设备（102），包括物理不可克隆功能（PUF）模块，以及适于从电子单元接收加密查询（a）的电路（108），从PUF模块读取在PUF模块的挑战下产生的数据，并且基于数据生成密码响应（ß），包含在数据中的随机噪声分量和密码查询（a），从而使电子设备（102）的认证）。本发明的优点在于，不需要将附加的随机发生器与电子设备（102）一起包括在内，因为由PUF模块提供的模糊输出可以被看作已经包含随机噪声分量。在一些加密方案中，随机噪声提供了达到更高级别的安全性的可能性，并且使得第三方在使用电子设备（102）期间生成的加密响应中找到模式的可能性最小化。本发明还涉及类似的认证方法。

摘要： A method for alleviating burn-in effect and enabling performing a start-up process in respect of a device comprising a plurality of challengeable memory elements, wherein the memory elements are able to, upon start-up, generate a response pattern of start- up values useful for identification as the response pattern depends on physical characteristics of the memory elements, the method comprising the step of, after start-up of the memory elements, writing a data pattern to the memory elements which is inverse to a response pattern that was previously read from the same memory elements. Thus, degradation of the PMOS transistors due to NBTI can be alleviated.
