TrustBuilder: Access Control and Authentication for Open Computing Systems

Automated trust negotiation is a new approach to access control and authentication for the open, flexible systems formed by sets of organizations that must dynamically form coalitions and work together to respond to unforeseen needs and opportunities. Automated trust negotiation enables open computing by assigning an access control policy to each resource that is to be made accessible to "outsiders"; an attempt to access the resource triggers a trust negotiation, consisting of the iterative, bilateral disclosure of digital credentials and related information.

An introduction to automated trust negotiation is available, targeted toward people without a background in security research.
