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.

39. A tamper-protected semiconductor module comprising:
-
a hardware module comprising one or more emitters for emitting a predetermined excitation that can be measured as a physical measurand, and one or more sensors for sensing the (back-) scatter of the excitation in form of the physical measurand in a contactless and/or contact-based manner, and a cocoon housing the hardware module, the cocoon being adapted to influence the (back-) scatter of the predetermined excitation to be sensed by the sensors. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 49, 50, 54, 55, 56, 57, 59, 60, 66, 69, 70, 71, 72, 73, 74, 75)

61. A method for manufacturing a tamper-protected semiconductor module comprising the steps:
-
providing a hardware module comprising one or more emitters for emitting a predetermined excitation that can be measured as a physical measurand, and one or more sensors for sensing the (back-) scatter of the excitation in form of the physical measurand in a contactless and/or contact-based manner, and housing the hardware module in a cocoon to obtain the tamper-protected semiconductor module, wherein the cocoon influences the (back-) scatter of the excitation sensed by the sensors in a way unique to the tamper-protected semiconductor module. - View Dependent Claims (62, 65)
