Security Enhanced Distributed Knowledge Management Architecture

From the emergence of Knowledge Management (KM) systems until today, the vast majority of the implemented systems have concentrated on a centralised architecture, which utilizes knowledge within a single organizational domain. Lately, there is much focus on alternative, distributed approaches, which attempt to overcome the single organization's KM paradigm, and develop inter-organizational knowledge exchange infrastructures. Effective management from a security perspective is always a serious and difficult to achieve challenge, especially when it comes to managing resources from cooperating autonomous domains. Security issues in Information Systems coalition enabling environments are treated in this paper and a secure distributed KM architecture is being presented.
