"Levels of trust:
          Forwarding, computing, and policy enforcement
                    in third-party networks"
            Ken Calvert, Lab for Advanced Networking
                     University of Kentucky


  Users of networks today have to trust service providers'
  infrastructure to perform functions such as forwarding.  When
  users rely on third parties for more advanced functions, however,
  interesting questions of trust may arise.  This talk will discuss
  problems and solutions using examples from our experiences with
  secure concast.
