Trusted virtual domains: toward secure distributed services

Abstract

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.
