Trust Scheme Interoperability: Connecting Heterogeneous Trust Schemes

The growing interconnectedness of computer systems has led to the need for a flexible approach to trust management. Many countries operate trust schemes to enable the automated assessment of the trustworthiness of information. But this assessment remains a challenge if the information was issued in a foreign trust scheme. An issue is the lack of a root of trust shared between the trust schemes. Other challenges are the heterogeneity of trust models used by entities operating in different legal and cultural environments.
