Abstract

With the rapid growth of digital computing and networking technologies, trust becomes an important aspect in the establishment of a secure digital system. Based on different reasons of trust, different trusted domains, possibly disjoint, are formed in a digital system, preventing the complete system from working improperly. What lacks therein are bridges that can link domains, across trust gaps to establish a complete trusted system. In this paper, we apply a methodology for establishing a trustworthy system through bridging disjoint domains of trust together. We illustrate how to analyze and design a trustworthy system by applying the methodology into a concrete example with regard to establishing a trustworthy middleware platform for component software.
