Semantics-Based Approach for Dynamic Evolution of Trust Negotiation Protocols in Cloud Collaboration.

Many techniques for addressing trust negotiation issues is little concerned with managing the dynamic evolution of trust negotiation protocols (policies), particularly in cases where there exist ongoing negotiations when a protocol has been changed. We propose an approach that automatically determines how consequences of changing a protocol affect ongoing negotiations. In particular, our approach allows to capture the semantics and intention of protocol changes, memorize and apply them in effectively analyzing the impact of protocol changes on negotiations.
