Abstract:
One of the various aspects of the invention is related to suggesting various techniques for improving the tamper-resistibility of hardware. The tamper-resistant hardware may be advantageously used in a transaction system that provides the off-line transaction protocol. Amongst these techniques for improving the tamper-resistibility are trusted bootstrapping by means of secure software entity modules, a new use of hardware providing a Physical Unclonable Function, and the use of a configuration fingerprint of a FPGA used within the tamper-resistant hardware.

Claim (Index 1):
A tamper-protected hardware module, comprising:\n a hardware structure providing a Physical Unclonable Function (PUF), the hardware structure being adapted to provide a response to challenges input to the PUF implemented in the hardware structure, a processor unit for providing, to the hardware structure implementing the PUF, at least one challenge, for which the correct PUF response by hardware structure implementing the PUF is known, wherein the processor unit is adapted to receive a respective PUF response for each challenge provided to the hardware structure implementing the PUF, and to verify integrity of the tamper-protected hardware module by checking whether the response to the at least one challenge for which the correct PUF response is known is matching the response received from the hardware structure implementing the PUF.
