Abstract: 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 chal- lenging when the objective is collaboration across organisa- tional boundaries. Numerous access control approaches exist today to address the cross-boundary control issues. How- ever 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 dicult. 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 secu- rity credentials could be folded to local security credentials through trust contracts.
