Schematize Trust Overlays and Management for Privacy Preservation in MANET

Mobile ad hoc Networks refers to the infrastructure less, resource poor wireless networks whose interaction is unplanned in such a way that location of participating nodes and parties can not be identifiable. The mobile devices are used by people to access services in various environments. Before two or more mobile networks ready to interact, they must trust that each will satisfy the security and privacy requirements of the other. In this paper, we schematize the role of trust overlays and its management, a systematic approach to build such trust overlay in MANET for privacy preservation. Our solution exploits the increasing availability of trusted computing hardware on open systems, including portable computers and mobile devices. Our proposal has emphasized that key pieces of these solutions are coming into a common place, as all mobile devices provide distributed mandatory access control. We also point out that tremendous challenges remain, such as how to set compatible security policies across administrative domains and how to derive a trust coefficient to build trust in MANET.
