Trusted virtual domains: toward secure distributed services

The focus of trusted computing efforts to date has been to create islands of trust in a sea of distrust, identifying these islands as dependable domains with a solid base that can be used for building applications upon which critical services depend. The aim of our work is to extend this solid base by building "bridges" among trusted islands, with such goals as enabling meaningful trade agreements between islands, enabling migration of individual island inhabitants, and enabling geography-independent affiliation among inhabitants of different islands.
