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： 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.
