One of the most difficult problems to be solved by metacomputing systems is to ensure strong authentication and authorization. The problem is complicated since the hosts involved ...
In the paper we present an overview of Saga Security System, a security architecture in open distributed systems. An agent in Saga Security System is called a Saga Agent. The auth...
The problem we address in this paper is how to detect an intruder moving through a polygonal space that is equipped with a camera sensor network. We propose a probabilistic sensor ...
This paper introduces the distributed MAC protocol Jade. We consider a multi-hop wireless network with a single communication channel in which a powerful adversary is able to jam ...
We claim that network services can be transparently added to existing unmodified applications running inside virtual machine environments. Examples of these network services inclu...
