Abstract: The present disclosure relates to configuring at least one pair of devices in a physical unclonable function (PUF) apparatus and reading out at least one pair of devices for determining a persistent random PUF output. The pair of devices may be readout by measuring a physical difference between the devices/components caused by random manufacturing differences, which may then be used to determine a persistence random PUF output. Configuring the pair of devices includes measuring the random manufacturing difference and, based on that measurement, setting a readout condition for the pair of devices, which dictates aspects of the readout process that should be used for that pair of devices. Each time the pair of devices is readout in the future, it may be readout in accordance with the condition that was set at configuration.

Abstract: A host computer (200-2) with a FPGA (300-2) is communicatively coupled to a configuration computer (100-2) via a communication network (150). The host computer receives target configuration data (122 from the configuration computer (100-2) in encrypted form. A scanner module that is associated with the host computer decrypts the target configuration data and scans it for malicious code. The module writes the target configuration data to the fabric area of the FPGA and thereby configures the FPGA accordingly, to enable execution of a target array application. The scanner module is associated with the host computer by being implemented as trusted execution environment, or as an on-array-processor.
