Ubiquitous computing (ubicomp) is about networked microprocessors embedded in everyday objects: not just cellphones and home appliances but also books, bookshelves, bus stops and bathtubs. This future is closer than you might imagine.

The insecurity of networked PCs is notorious. If we deployed ubicomp systems as vulnerable as PCs, the risks for society would be catastrophic. How can we do better, and what are the new problems? In a very accessible style, this book provides a coherent framework to make sense of the many issues at stake.

Features include:

* An introduction to the state of the art in ubicomp research.

* A readable primer on security and cryptology.

* An up-to-date technical treatment of ubicomp security, including a sceptical look at Bluetooth and 802.11.

* "Peer-to-peer" and ad-hoc networking.

* An in-depth discussion of specific, cutting-edge solutions.

* An extensively annotated bibliography.

Security for Ubiquitous Computing combines clarity, brevity and authority. It will appeal to developers and researchers in ubiquitous computing, wireless and ad-hoc networking, wearable computing and related areas. Because it is readable and self-contained, it will also prove valuable to managers, analysts, technology watchers and end users who want to understand the new opportunities and risks of ubicomp.

Written for developers and researchers, this book describes the current state of ubicomp research and provides a concise introduction to general issues in security and cryptology. Technical aspects of ubicomp security are then discussed, as are peer-to-peer and ad-hoc networking. Chapters concentrate on authentication, confidentiality, integrity, availability, anonymity, functions, and existing network solutions. The emphasis throughout is on security solutions.

"...a remarkably readable introduction to the topic...rich in background material." (IEEE Network, New Books &Multimedia Column, November 2002)

This title provides a technical overview of the state-of-the-art in security research as applied to ubiquitous computing systems.

* Describes the security issues in peer-to-peer networking, a new technology that is gaining prominence in the media with applications such as Napster and ICQ Chat

Computer sind allgegenwärtige Begleiter unseres Alltags - in Telefonen, Waschmaschinen, Fernsehgeräten, Heizungssystemen, Smart Cards und vielen anderen Geräten. In diesem Buch wird beschrieben, wie alle diese Systeme über drahtlose Netzwerke miteinander kommunizieren können. Insbesondere wird auf die derzeit entwickelten Techniken und Protokolle eingegangen, mit denen sich absichern läßt, daß die Systeme vor unberechtigtem Zugriff geschützt sind und die Daten den richtigen Empfänger erreichen. Dieser Band ist weder ein "Kochbuch" mit Anleitungen zur Implementierung noch ein enzyklopädisches Handbuch. Es bietet Ihnen vielmehr einen Rahmen zum Verständnis der Technologie, eine Kategorisierung der wichtigsten Probleme und eine tiefgründige Diskussion einiger spezifischer Lösungen. Nützlich ist die allgemeine, gut verständliche Einführung in die Sicherheitstechnik und die Grundlagen der Kryptographie.
