Automated Trustworthiness Management for Database Software Components

Component-based software architectures are being used more and more often in industry, creating new kinds of dynamic business relationships between the integrators and their partners in developing the components. In this kind of business it is especially important to ensure that both the components and the co-operation partners are trustworthy. One method of component trust management is to include in the software architecture functions that take care of loading and updating the components, and monitor their trustworthy operation. We introduce a novel trust management framework for the middleware layer and demonstrate its functionality using embedded software components. We explain the functionality of our trust management system and demonstrate its application in managing software components and utilizing database services for both management of component properties and delivery of new components from trusted sources.
