On Improving the Performance of Role-Based Cascaded Delegation in Ubiquitous Computing |
Abstract | ||
---|---|---|
In ubiquitous computing environments, computing devices may have small storage units and limited bandwidths. A trust management system needs to be efficient in order to keep communication and computation costs low. The trust establishment mechanism needs to be flexible, because credentials are usually scattered at distributed locations. Also, the authorization process needs to be decentralized and support dynamic resource-sharing in order to handle emergency situations. We discuss how to improve the efficiency, flexibility, and privacy of role-based cascaded delegations in a ubiquitous computing environment. Operations for managing delegation chains in the role-based cascaded delegation (RBCD) model are presented. These operations can significantly improve the performance of the decentralized delegation in the RBCD model, without increasing the management overhead. |
