It has been shown that a Security Association (SA) established by strong authentication between a node pair in a Mobile Ad Hoc Network (MANET) should not depend on link connectivity [1]. While stale (long) SAs should be renewed, SA duration should be managed by a security policy and based on a trust model regardless of link intermittence. Both the security policy and the trust model are modules of...
Maintaining security associations (SA) in mobile ad hoc networks (MANET) is challenging due to their intrinsically open, dynamic, and decentralized nature. Bandwidth limitations arising from both the physical characteristics of the wireless medium and the control overhead required to maintain routes in a network with changing topology add another level of difficulty to the problem. While establishing...
A Security Association (SA), established by strong authentication, between a node pair in a Mobile Ad hoc Network (MANET) could be lost when its route is disconnected. In contrast, in good channel conditions and stable topology, routing protocols such as the Optimized Link State Routing (OLSR) do not refresh routes periodically, and in doing so, an SA bound to these routes could become stale and out...
