2nd Annual PKI Research Workshop
Krishna Sankar introduced the Transports for Trust panel with a selection of definitions of trust, emphasizing that trust is multidimensional, dynamic, and context-dependent. Irving Reid surveyed trust models and argued for an approach combining shared policy services with support for a variety of trust transports. Scott Cantor gave an overview of Shibboleth, including a one-slide snapshot of Shibboleth's use of SSL. Slava Kavsan outlined the Liberty Alliance "circles of trust" model, mapping it to SAML and setting it in the context of a typology of trust. This typology is further developed in the Liberty Trust Model Guidelines document, available at http://www.projectliberty.org/specs/. Carlisle Adams gave an overview of the development of SAML and outlined projected improvements for v1.1 (incremental fixes) and 2.0 (major additions).
