Dynamic and Distributed Trust for Mobile Ad-Hoc Networks

摘要

Future battlefield networks will involve thousands of heterogeneous nodes operating under rapidly changing connectivity, and resource (bandwidth, energy, computation, etc.) constraints. Mobile Ad-hoc networks (MANET) form the basis for current and future military networks. Trust and trust establishment among communicating nodes (soldiers, vehicles, UAVs, satellites) and sensor nodes is the absolutely starting point for establishing any such network. The network management system needs to frequently validate trust, frequently defend against attacks, quickly isolate compromised nodes, and quickly establish trust in dynamically collaborating group (topology changes). In this paper we provide our solution to the problem of establishing and maintaining trust relations within a MANET, in a manner that satisfies both the dynamic and distributed constraints of the problem.
