Securing Resources in Collaborative Environments: A Peer-to-peer Approach


K. Berket, A. Essiari and M. R. Thompson


We have developed a security model that facilitates  control of resources by autonomous peers who act on behalf of collaborating users. This model allows a gradual build-up of trust. It enables secure interactions among users that do not necessarily know each other and allows them to build trust over the course of their collaboration. This paper describes various aspects of our security model and describes an architecture that implements this model to provide security in pure peer-to-peer environments.
