Denial-of-service resilience password-based group key agreement for wireless networks

A provably secure cluster-based hybrid hierarchical group key agreement for large wireless ad hoc networks

“…Key management in distributed/contributory-GKA are less difficult to deal with in each subgroup/cluster compared to the whole ad hoc network. So most recent works [18,20,21,25,26,30,31,35,39,[40][41][42] adopted subgroup/cluster based approach, in which the whole group is divided into clusters. Distinct controllers are utilized to control every cluster which minimizes the issue of imposing the work on a single point.…”

“…The majority of CK-GKAs' [18,20,21,25,26,30,31,35,39,[40][41][42] presume a hierarchical framework of the clusters or hierarchical structure, then execute a natural key agreement schemes such as, D-H [34] or the Burmester and Desmedt (BD) [3] GKA scheme, or a variety GKA schemes [3,7,16,[35][36][37][38][39] is at first implemented locally in each cluster, after that utilize these CKs in the next level with equivalent or an alternate key agreement scheme among CHs' to generate the whole group key. For further information on a comparison of the existing protocols [18,21,25,26,28,30,31,33,43] in this direction, one can refer to Table 2, summary of the key characteristics of cluster based protocols.…”

“…Notice that this paper assumes that the cluster structure has already been established (includes the amount of levels in the cluster hierarchy, formation of clusters [20,21,25,26,[30][31][32][33] and the selection of CHs) and thus does not consider overhead computation during the cluster-setup phase.…”

A Survey on Wireless Sensor Networks Security with the Integration of Clustering and Keying Techniques

“…Teo and Tan [7] proposed the Group Key Agreement (GKA) protocol for Circular Hierarchical(CH) group model (GKA-CH) [5]. and the Burmester-Desmedt [6] GKA protocol is applied in every layer of a circular-hierarchical group structure.…”

“…The password-based GKA protocol for hierarchical group models (PB-GKA-HGM) is proposed by Teo and Tan [7]. This protocol creates a hierarchical structure based on three main entities: the main controller C in highest layer, various subgroup controllers (Si) and several members (M) in every subgroup.…”
