There is provided a cryptographic key determination device for determining one or more cryptographic keys in a cryptographic device, the cryptographic device being configured to execute one or more test programs, the cryptographic device comprising one or more components (-), each component (-) being configured to generate static and dynamic data, the dynamic data being generated in response to the execution of the one or more test programs, wherein the cryptographic key determination device comprises: a data extraction unit configured to extract at least one part of the static data and at least one part of the dynamic data generated by the one or more components (-), and a key generator configured to combine the at least one part of static data and the at least one part of dynamic data, and to determine the one or more cryptographic keys by applying a cryptographic function to the combined data.

Methods and devices for secure secret key generation

A circuit for a Synthetic Physically Unclonable Function, acronym SPUF, in a computer device, wherein the circuit is configured to receive data from a plurality of hardware sensors and/or actuators accessible in the computer device; to determine deviations in the data; to determine a multivariate distribution of the deviations and to determine an identifier from the multivariate distribution. In described developments, deviations comprise random errors, statistical moments in data originating from sensors and/or actuators amongst accessible ones in the computer device can be selected, and entropy can be maximized. Computer program product embodiments are described.
