Abstract
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.
