Trust Management and Authorization
Framework for B2B
(PASTELS) [back to
projects page]
The goal of this R&D project is to research on Trust Establishment,
Trust Management and Trust Monitoring for e-Services (web services)
in an Internet-based B2B environment. The focus is on digital
credentials and fine-grained authorization at the service level as
basic foundation for Trust Services.
Digital credentials (X.509 identity
certificates and Digital Signed XML attribute credentials) are
exchanged among businesses, on the Internet, to establish trust and
to underpin trust during business transactions. Digital credentials
can be easily managed at the user side (PASTELS browser plug-in) and
at the service provider site (PASTELS credential usage monitoring
service).
Enterprises can deal with trust management and
fine-grained access control for e-Services by using flexible
fine-grained Validation and Authorization Services (PASTELS
policy-driven authorization framework). A prototype has been built,
based on an e-Services Marketplace scenario and Intellectual
Properties generated.
