A Proposal for Trust Management in Coalition Environments

It is well-recognized that for large catastrophes such as tornadoes, earthquakes, disease outbreaks, or aftermath of a war, coalitions that can coordinate and exploit resources and capabilities of many organizations are required to respond effectively. It is our thesis that in such coalition environments, classical security policies and access-control mechanisms need to be augmented by incorporating the notion of risk and trustworthiness of the parties involved. In this paper, we systematically analyze what trust is, highlight challenges in incorporating the notion of trust in coalition environments, and put forward a proposal to address these challenges.
