A security policy system for mobile autonomic networks.

An autonomic security system is indispensable for the operation of an autonomic network. Policies are basic stones in building autonomic systems. In this paper, we introduce our model of mobile autonomic networks. Accordingly, we propose a security framework for building autonomic security systems. In this framework, we discuss a trust model based on node communities, an authentication model based on node categorization, and a secure relation model based on both trust and node capabilities. A network evolution model is eventually presented as the working context of an autonomic security system. Afterwards, we explain our vision of autonomic policy systems, and relevantly present solutions for security policy representation and manipulation. Finally, we define an authorization model for mobile autonomic networks, before elaborating an example of the implementation and the negotiation of a relevant access control policy.
