On mechanism supporting situational awareness of a tactical ad-hoc network node

The article presents the concept of a system that can increase information assurance in tactical mobile ad-hoc networks. Tactical MANET, due to its specification, requires application of advanced mechanisms for ensuring security in a degraded environment. The authors provide a brief survey of related works and present their own concept of authentication and trust management mechanisms as well as their integration for creating a security system. The proposed system is composed of selected security mechanisms allowing for intrusion detection, inference and reaction on detected threats.
