What is Trust on an insecure network?
If one considers a more complex case where modern business changes so quickly, and favors outsourcing plus ad hoc relationships, then one must anticipate additional challenges. In considering unstable relationships to remote mobile users, Omar, Challal, and Bouabdallah (2009) strive to create networks with limited planning and no centralized control. The model for their mobile ad hoc network (MANET) uses wireless links and a trust model that builds a network of trust by tracking individual links. This would lead to public certificates and a form of trust similar to reputation in other systems. However, MANET envisages the extension to public key certificates that do not require management or trusted authorities. Should this concept grow, it might well become very important in the future. It might also provide value within a closed system in a department or enterprise.
With all of this dynamic interaction, how can traditional network management and security cope?
