  • Patent number: 11206145
    Abstract: An integrated circuit and a method of configuring a plurality of integrated circuits are disclosed. Each integrated circuit comprises a cryptographic key specific to it. Each integrated circuit comprises a cryptographic key specific to it. Each cryptographic key can be generated on the respective integrated circuit using a physical unclonable function and data associated with the cryptographic key, e.g. a configuration message comprising instructions for generating the cryptographic key using the physical unclonable function. The cryptographic key specific to the integrated circuit is not stored on the integrated circuit. Each of the plurality of integrated circuits are configured using a data file that is encrypted with the respective cryptographic key specific to the integrated circuit, circuit.

  • Patent number: 10027482
    Abstract: A method and a cryptographic device for encrypting/decrypting an input message by using an algorithm having as entries, said input message, a cryptographic key, and a complementary unique value used as parameter of the algorithm. The output data is formed by the input message decrypted/encrypted by the algorithm using the cryptographic key and the complementary value. The latter is determined on the basis of a unique value physically bound to an electronic device by using a physically unclonable function (PUF) which is inherent to this device and which is used to generate this unique value from a plurality of physical measurements carried out on components integrated in said device.

  • Publication number: 20180123807
    Abstract: A method for generating a value inherent to an electronic circuit by measuring a physical quantity carried out on components of the electronic circuit, comprising calculating and associating to each component at least one value derived from a series of measurements carried out on said component, the calculating of the at least one value comprising: determining a statistical value from said series of measurements, defining said value derived from the series of measures as being said statistical value or an uncertainty range calculated from said statistical value, forming a collection of invariable pairs of components, selecting, in said collection, pairs so that said values associated to the components of each one of these pairs are spaced from each other by at least a setpoint value, generating said value inherent to the electronic circuit by concatenating the results of comparisons based on at least one of the values associated to the components of each selected pair, and data among which at least one is der

  • Publication number: 20170269151
    Abstract: A method to control aging of a system on chip comprising one or more devices including semiconductor circuit components and at least one aging controller monitoring electrical signals circulating inside the system on chip. The method comprises steps of stressing at least one device of the system on chip by varying hardware parameters related to its operating mode, comparing at least one parameter associated with an electrical signal produced by the at least one device with a reference parameter to determine a difference corresponding to an operating age value of the at least one device, if the operating age value equals or exceeds a threshold age value, determining a stress state value and modifying the operating mode of the at least one device according to the stress state value. A system on chip performing the method is also disclosed.
