This article gives a brief look at the history of security in computing and a look at some of the existing security techniques. New threats introduced by pervasive computing are considered and security of existing link-layer protocols and applicability of higher-layer protocols is reviewed. Possible directions of the future of the security of pervasive computing are also considered.

To the inspired observer, computer science nowadays appears to be challenged (and driven) by technological progress and quantitative growth. Among the technological progress challenges are advances in sub-micron and system-on-a-chip designs, novel communication technologies, microelectro-mechanical systems, nano and materials sciences. The vast pervasion of global networks over the past years, ...

The idea behind pervasive computing is that embedded and invisible technology calms our lives by removing the annoyances. Everyday life, however, is shaped by what people do, how they do it, and how they perceive what they are doing. As a consequence everyday life is difficult to grasp in computational terms. A look at the pervasive computing literature indicates that in a number of pervasive c...

Pervasive computing envisions applications that provide intuitive, seamless and distraction-free task support for their users. To do this, the applications combine and leverage the distinct functionality of a number of devices. Many of these devices are invisibly integrated into the environment. The devices are equipped with various sensors that enable them to perceive the state of the physical...

The talk will cover recent advances in micro-sensor technology including hardware platforms, networking and collaborative computing methods, as well as middleware and PSC applications. Key accomplishments from related DARPA programs will be presented. Challenges in transforming sensor data to knowledge supporting decision making will be covered. Potential approaches to dramatically reduce devic...

-Pervasive computing integrates digital and physical devices. Users can access digital data and applications from the environment as easily as accessing them through their computers. The system has to be flexible to various kinds of faults and should be able to function even though the fault occurs. This paper deals with various classes of failures, their implication to pervasive computing, the...

Pervasive computing appears like a new computing era based on networks of objects and devices evolving in a real world, radically different from distributed computing, based on networks of computers and data storages. Contrary to most context-aware approaches, we work on the assumption that pervasive software must be able to deal with a dynamic software environment before processing contextual ...

Various forms of pervasive computing environments are being deployed in an increasing number of areas including healthcare, home automation, and military. This evolution makes the development of pervasive computing applications challenging because it requires to manage a range of heterogeneous entities with a wide variety of functionalities. This paper presents Pantagruel, an approach to integr...

I n 1999—almost a decade after Mark Weiser wrote his seminal article1—the then-popular search engine Alta Vista found seven hits in response to a “pervasive computing” search query. Today, Google responds with more than 1,900,000 search results (or 2,300,000 for “ubiquitous computing”). The dawning of this research field is over—we’ve reached the break of day! The question now is, what’s next? ...
