Secure Dynamic Community Establishment in Coalitions

This paper presents a mission management architecture and a policy-based methodology for specifying and assigning missions to be accomplished by a secure Community of Interest (CoI). By using policies and roles to specify missions we enable dynamic mission assignment and adaptation. The specific entities forming the community may not be known in advance, so they have to be discovered, authenticated and assigned to roles. Policies are needed to define what services and resources a role can use from another role; what information can be exchanged, and the protocols to be used for communication; and, how to deal with heterogeneity of communications, security mechanisms, etc.¹
