A Service Oriented Trust Development Platform

A Trust Development Platform that offers services for the generation and interpretation of trust based on the concept of ecosystem's federation is presented. Trust federation schemes allow to define bonds of confidence between systems managed under different domains and policies. Each ecosystem has a trusted service provider that will automatically deliver services for the local domain following its own security policies. Ecosystem's federation leads us to the federation of trusted services providers and therefore, to the development of federated trust systems. Unlike solutions based on global trust policies, the proposed architecture is easy to deploy and use, and conforms to the requirements for each environment. Moreover, an ecosystem's federation is also feasible because a common language is shared, XML, and a plethora of related standards are based on it. SOA and Web Services are intimately related to federation, so trust development is now something almost tangible.
