Security issues have always limited the way we do things. In an organisation we provide security by granting privileges to either identities or roles. However this becomes more challenging when the objective is collaboration across organisational boundaries. Numerous access control approaches exist today to address the cross-boundary control issues. However an optimal approach would be to fold remote security credentials into local security credentials, thereby bridging the gap that makes decentralised security policies for multi-domain collaboration difficult. In this paper, dynamic trust negotiation is presented as a possible optimal approach that provides support for decentralised access control. We show how trust pathways can be established and how remote security credentials could be folded to local security credentials through trust contracts.
