Security services efficiency in disadvantaged networks

Modern coalition operations require efficient cooperation between partners of allied forces. They usually rely on their national systems equipped with software solutions supporting interoperability. Federation of systems built for the purpose of such operations assumes however independence of particular individual ones. In order to support efficient exchange of information between allies there are necessary federated software solutions promoting secure cross-domain information exchange. Lately the concept of Federated Mission Networking following Service Oriented Architecture (SOA) is being developed by NATO. In terms of secure information exchange for SOA-based services it proposes to use Web Authentication standard based on WS-Federation. In the article the authors present the results of tests of this standard efficiency in disadvantaged network environment built with PR4G radios. The architecture of the solution is presented with necessary information exchange relations and their invocation times.
