A Framework for a Trusted Environment for Virtual Collaboration

Trusted computing has assumed major significance since the advent of internet based commerce and peer to peer communications. Trust is the belief that a peer has another peer in a given context. This paper addresses both identity trust which establishes the identity of another party and behaviour trust which answers the question ’Do you believe that the entity will behave as you expect it to?’ It develops complete definitions of context and time dependant trust and reputation and develops trust models, trust relationships of a peer.
