Abstract
Trust-based access control is the idea of using a model of human notions of trust and community as the basis for assigning privileges. Risk analysis is used to determine how much trust is required to assign a particular privilege in trust-based access control. Other topics mentioned are the validation of the model, investigation of how continuous probability density functions may be reasoned about in resource constrained environments and the creation of a general purpose policy language to allow the specification of policies.
