BambooTrust: practical scalable trust management for global public computing

Global public computing platforms, such as PlanetLab, grid computing systems, and XenoServers, require facilities for managing trust to allow their participants to interact effectively in an open and untrusted environment. In this paper, we describe BambooTrust, a practical, high-performance distributed trust management system for global public computing platforms. We present our peer-to-peer architecture, based on the XenoTrust model and the Bamboo distributed hash table. We describe the initial BambooTrust implementation and deployment, and demonstrate that the system performs and scales more than adequately well by means of experimental evaluation.
