Are our Educational Technology Systems Secure?

Pretending that Systems Are Secure

side of the picture—the computers themselves are only part of the system. IEEE Security & Privacy has covered these topics in the past, but usually from the perspective of computing, not society. Can we make it easier for human users to correctly trust what their computers are telling them? Can we make it easier for human programmers to write code that achieves desired functional and performanc...

Secure Communication in Shotgun Cellular Systems

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

"Our educational institutions have failed ..."

Neben den Hochschulen, als klassische Ausbildungsstätten für Informatiker mit jeweils unterschiedlicher Ausrichtung, sind eine große Zahl von kommerziellen Trainingsanbietern vorhanden. Meist werden in Weiterbildungskursen spezielle Themen aus dem IT-Bereich angeboten. Eine Tendenz ist derzeit zu erkennen, auch Grundlagenwissen in Kursen zu vermitteln. Ein dreistufiges Qualifizierungsprogramm i...

How Secure are Current Mobile Operating Systems?

There are numerous initiatives to use mobile devices as so-called “trusted pocket signers” to produce electronic signatures. The actual signature is generated by means of a conventional signature card. The mobile device serves as the card reader, storage device for the document to be signed and as a display for the signature application. The operating system used on the mobile device has thus a...
