We describe the design and implementation of a trust-management system Soutei, a dialect of Binder, for access control in distributed systems. Soutei policies and credentials are w...
In-network aggregation is an essential primitive for performing queries on sensor network data. However, most aggregation algorithms assume that all intermediate nodes are trusted...
Wireless sensor networks are designed to extract data from the deployment environment and combine sensing, data processing and wireless communication to provide useful information ...
Abstract-- Sharing data among collaborators in widely distributed systems remains a challenge due to limitations with existing methods for defining groups across administrative dom...
This paper introduces a context-aware authorization architecture that is designed to augment existing network security protocols in an Intranet environment. It describes the archi...
