In hardware implementation of a cryptographic algorithm, one may achieve leakage of secret information by creating scopes to introduce controlled faulty bit(s) even though the algorithm is mathematically a secured one. The technique is very effective in respect of crypto processors embedded in smart cards. In this paper few fault detecting architectures for RC4 algorithm are designed and implem...

In this video presentation we demonstrate the STARS platform for realizing computer augmented tabletop games within a smart Roomware® environment. STARS dynamically couples multiple types of interaction devices such as personal digital assistants (PDAs) or headsets with an interactive game table. STARS augmented tabletop games provide a number of features like dynamic game boards or private com...

Introduction: Anticipation of events such as changes in traffic light signals and preparing to brake or accelerate are critical behaviors during driving. Smart vehicles, equipped with on-board Brain-Computer Interface (BCI), could decode the driver's intention to perform an action from his brain activity, thus, enable a possibility to enrich the interaction between the car and its driver [1]. W...

The power electronics industry and the semiconductor industry, inseparably intertwined with one another, are facing unprecedented efficiency, cost, construction and thermal challenges which provide many opportunities for innovation. These industries are in the focal point of the “energy challenge” a multifaceted problem that involves mobile and cloud infrastructure systems, Internetof-Things, r...

The design and implementation of a medical implantable device for bladder monitoring is presented. A network of accelerometers is to be implanted in-between the outside bladder muscle and the mucous membrane. A pressure sensor is also implanted in this submucosal layer to obtain intraluminal pressure readings. The sensor system is powered by an implanted battery and provides a wireless communic...

An attribute-based signature (ABS) is a special digital signature created using a dynamic set of issued attributes. For instance, a doctor can sign a medical statement with his name, medical license number and medical speciality. These attributes can be verified along with the signature by any verifier with the correct public keys of the respective attribute issuers. This functionality not only...

This paper describes a prototype system that displays synchronous workplace awareness information using the ambient technology paradigm. It focuses on making people aware of the nature and volume of interactions that have taken place within a workgroup. The visualisation uses simple graphics based on a maritime flags metaphor, is displayed in the Windows Active Desktop and is designed to be as ...

1 Einleitung Die Digitale Gesellschaft und die Entwicklungen, die mit dem Begriff Web 2.0 zusammengefasst werden, führen zu erheblichen Veränderungen in Unternehmen, im Privaten und ebenso an Hochschulen. Die Wissensvermittlung an Hochschulen beruht vielerorts auf Powerpoint-Folien, die weder webgestützt sind noch Interaktion ermöglichen oder unterstützen. Alternative Softwareansätze (z. B. pre...

The utilization of nonmobile, distributed sensor and communication devices by a team of mobile robots o ers performance advantages in terms of speed, energy, robustness and communication requirements. Models of mobile robots with on-board sensors, a communication protocol and the S-Net system are established. Algorithms are de ned for the S-Net which perform cooperative computation and provide ...
