摘要： A message is signed using a PUF without having to exactly regenerate a cryptographic key. Another party that shares information about the PUF is able to verify the signature to a high degree of accuracy (i.e., high probability of rejection of a forged signature and a low probably of false rejection of a true signature). In some examples, the information shared by a recipient of a message signature includes a parametric model of operational characteristics of the PUF used to form the signature.

摘要： A method is used to reliably provision and re-generate a finite and exact sequence of bits, for use with cryptographic applications, e.g., as a key, by employing one or more challengeable Physical Unclonable Function (PUF) circuit elements. The method reverses the conventional paradigm of using public challenges to generate secret PUF responses; it exposes the response and keeps the particular challenges that generate the response secret.

摘要： Physical Unclonable Functions (PUFs) for authentication can be implemented in a variety of electronic devices including FPGAs, RFIDs, and ASICs. In some implementations, challenge-response pairs corresponding to individual PUFs can be enrolled and used to determine authentication data, which may be managed in a database. Later when a target object with a PUF is intended to be authenticated a set (or subset) of challenges are applied to each PUF device to authenticate it and thus distinguish it from others. In some examples, authentication is achieved without requiring complex cryptography circuitry implemented on the device. Furthermore, an authentication station does not necessarily have to be in communication with an authority holding the authentication data when a particular device is to be authenticated.

摘要： Summarising this invention relates to a method for authenticating a device using an authentication station, said device providing a capability to accept a challenge value from the authentication station and return a response value to the challenge value to the authentication station that depends on fabrication characteristics of the device, the method comprising: identifying the device, including accepting identification data at the authentication station from the device to be authenticated; determining authentication data characterizing one or more pairs of challenge and response values associated with the identified device that were previously obtained by a trusted authority in communication with the device, wherein said retrieving of the data does not require communication between the authentication station and the trusted authority after identifying the device, and wherein the authentication data comprises model parameters sufficient to predict a response value for each of a plurality of challenge values.; providing a first challenge value from the authentication station to the device; accepting a first response value at the authentication station from the device; determining whether the pair of the first challenge value and the first response value sufficiently match the authentication data.
