Access Control Agnostic Trust Negotiation Decision Engine

Dynamic open environments demand trust negotiation systems for unknown entities willing to communicate. A security context have to be negotiated gradually in a fair peer to peer basis. Trust negotiation engines are driven by decision engines that lack of flexibility: they depend on the implementation, policies languages or credentials types to be used. In this paper we present a trust negotiation engine agnostic regarding policies and rules. The engine is based on iterative weighted Multidimensional Scaling to assist a mobile device during a trust negotiation.
