Using Cryptography in Trust Computing for Networked Communications

The authors highlight some major difficulties encountered by current approaches that try to model trust computing in a realistic networked communications system. They characterize these approaches as top-down since they assume that trust is universal and readily quantifiable. Their main concern with these approaches is that their quest to define a universal trust often ends up with a loose, context-dependent definition of trust value. Based on this shortcoming of the top-down approaches, they propose another consideration of trust for networked communications.
