Building Trust Territory in Ad Hoc Networks

Building trust has been recognized as a new security approach for wireless distributed networks. In the paper, we try to provide a completely new view by building trust territory in ad hoc networks. The concept of trust territory is addressed and the approach to build trust territory is also discussed. A trust territory contains all nodes trusted by the node. It is considered secure to communicate with nodes in the trust territories. Theories of sets, relations and graphs help to build trust territories. Trust territory could work in all layers of networks, so its potential for future applications is very promising.
