A trust-based security architecture for tactical MANETS

Security is a main concern in the establishment of tactical MANETs. Literature is abundant in defining protocol extensions to provide more secure MANET communications. Also many techniques have been developed to identify different types of network attacks, such as the wormhole attack, for example. However, all these security solutions are designed for specific routing protocols. In the absence of a generic security architecture, nodes from different MANET domains cannot cooperate and benefit from security advantages across the entire network, such as secured inter-domain routing, etc.
