摘要： In systems for establishing a cryptographic key depending on a physical uncloneable function (PUF) it may be a problem that internal information correlated with the cryptographic key is leaked to the outside of the system via a side-channel. To mitigate this problem a cryptographic system for reproducibly establishing a cryptographic key is presented. The system comprises a physical system comprising a physical, at least partially random, configuration of components from which an initial bit-string is derived. An error corrector corrects deviations occurring in the initial bit-string. Through the use of randomization the error corrector operates on a randomized data. Information leaking through a side channel is thereby reduced. After error correction a cryptographic key may be derived from the initial bit-string.

摘要： An electric physical unclonable function (PUF) (100) is provided comprising a semiconductor memory element (110) connectable to a PUF control means for reading content from the memory element and for deriving at least in part from said content a digital identifier, such as a secret key. Upon powering the memory element it settles into one of at least two different stable states. The particular stable state into which the memory element settles is dependent at least in part upon random physical characteristics of the memory element introduced during manufacture of the memory element. Settling of the memory element is further dependent upon a control input (112) of the memory element. The electric physical unclonable function comprises shielding means (142, 144) for shielding, during a time period including the power-up of the memory element and lasting at least until the settling of the memory element, the control input from receiving control signals upon which the particular stable state into which the memory element settles is dependent. In this way, the dependency of the memory element on its physical characteristics is improved, and dependency on possibly irreproducible control signals is reduced.

摘要： Systems for generating an identifying response pattern comprising a memory (120) used as a physically unclonable function configured for generating a response pattern dependent on physical, at least partially random characteristics of said memory may be vulnerable to freezing attacks and to aging. A memory-overwriting device (110) configured for overwriting at least a first portion of the plurality of memory locations to obscure the response pattern in the memory avoids freezing attacks. An anti-degradation device (160) configured to write to each respective location of a second portion of the plurality of memory locations an inverse of a response previously read from the memory reduces the effects of aging.

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.
