In a traditional PKI, the trust associated with a public key is expressed in binary either by 0 or 1. Alternatively, several authors have proposed trust metrics to evaluate the confidence afforded by a public key. However their work has a static point ...

Two main approaches for network intrusion detection are misuse detection [6] and anomaly detection [11]. The limitation of the misuse approach is that cannot effectively detect new patterns of intrusions that are not precisely encoded in the system [11]...

Today, although the system supports for developing distributed applications become mature, they are inadequate for mobile environments where the runtime resources vary considerably or even disappear spontaneously. The objective of our work is to provide ...

This paper presents an efficient technique for placement and routing of sensors/actuators and processing units in a grid network. Our system requires an extremely high level of robustness and efficient power optimization techniques. By modeling the ...

Network processors are embedded system-on-a-chip multiprocessors that are optimized to perform simple packet processing tasks at data rates of several Gigabits per second. To meet the performance demands of increasing link speeds and more complex ...

Flash memory based embedded computing systems are becoming increasingly prevalent. These systems typically have to provide an instant start-up time. However, we observe that mounting a file system for flash memory takes 1 to 25 seconds mainly depending ...

E-commerce as well as B2B applications are essentially based on interactions between different people and organizations (e.g. industry, banks, customers) that usually exploit the Internet as communication media. Web Services provide a mean to deal with ...

Peer-to-peer (P2P) has become an important computing model because of its adaptation, self-organization and autonomy etc. But efficient organization of the nodes in P2P networks is still a challenge needs to be addressed. Node clustering is a mechanism ...

Exchange of private information content among a large number of users via E-mail List Services is becoming increasingly common. In this paper we address security requirements in that setting and develop a new protocol, SELS (a Secure E-mail List Service)...

In recent years, exciting technological advances have been made in development of flexible electronics. These technologies offer the opportunity to weave computation, communication and storage into the fabric of the every clothing that we wear, ...
