Distributed delegation library for Web Services
A Trust Management and Trust Negotiation framework for SOAP-style and REST-style Web services and multi-agent systems, available as open source software and usable in different application scenarios. The framework allows users to create multiple levels of delegation of access rights for protected resources. It also allows to negotiate the incremental disclosure of credentials, among initially untrusted parties. It defines various certificates, for binding names, permissions and oblivious attributes to users, adhering to relevant standards, such as WS-Security, SAML and XACML.
