Hardware Security Concept for Spontaneous Network Integration of Mobile Devices

In this article we introduce an architecture of a mobile device that enables safe and authenticated data-transmission in a spontaneously configured network environment. The usage of this device is illustrated by a number of examples. The hardware and software components are presented. Particular, we compare Bluetooth and Infrared (IrDA) wireless networking technology, explain the usage of biometrics recognition methods, clarify the choice of the cryptographic module and consider possible platforms for the integration of this trustworthy device into a ubiquitous environment. Subsequently a first realization of the concept will be explained. Referring to feasible possibilities of realization, different attack scenarios together with appropriate solutions are considered.
