First Claim
Patent Images
1. 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, anda cocoon housing the hardware module, the cocoon being adapted to influence the (back-) scatter of the predetermined excitation to be sensed by the sensors.

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.
