Large grid installations require global access to massive data stores. Parallel file systems give high throughput within a LAN, but cross-site data transfers lack seamless integra...
The usability of access control mechanisms in modern distributed systems has been widely criticized but little studied. In this paper, we carefully examine one such widely deploye...
A cross-layered slotted ALOHA protocol is proposed and analyzed for distributed estimation in sensor networks. Suppose that the sensors in the network record local measurements of ...
An outstanding security problem in mobile agent systems is resource access control, or authorization in its broader sense. In this paper we present an authorization framework for m...
The intent of peer data management systems (PDMS) is to share as much data as possible. However, in many applications leveraging sensitive data, users demand adequate mechanisms to...
