Abstract

Dynamic trust models and replication approaches that adequately address the security needs of wireless cognitive ad hoc networks have proven quite difficult to develop. As established by Qusay H. Mahmoud in the 2007 book titled Cognitive Networks: Towards Self-Aware Networks [1], reliable and robust security models need to be developed. The inherent decentralized nature of ad hoc networks and their collaborative services give rise to a series of vulnerabilities that can be exploited by malicious entities [5]. Instead of assuming a "home egualis" approach to security, where there is no centralized structure or governance, a Byzantine generals' approach could be used. This centralized approach has been successfully used to provide fault tolerance to distributed systems [10] [11] [12]. This paper presents a novel approach to distribute trust data utilizing the 3m+1 solution to the Byzantine general's problem.
