An Mobile Ad-hoc NETwork (MANET) is formed when group of mobile wireless nodes collaborate between them to communicate through wireless links in the absence of the fixed infrastructure and any centralized control. These characteristics make it able to adapt and operate in difficult conditions, but also vulnerable to new security attacks not present in a traditional wired network. In this paper a new approach to secure MANETs has been proposed. The authors' solution is based on their efficient trust model and distributed algorithm to clustering network in order to distribute role of Certification Authority (CA) in each cluster. They use fully self-organized security and monitoring process to supervise behaviors of nodes with low trust level.
