Abstract
Group key management (GKM) refers to the actions taken to update and distribute the group key upon members joining and leaving a multicast group. Although there exist several GKM schemes, they are not readily applicable to wireless mesh networks (WMNs) due to many differences between WMNs and wireline networks. We present a review of existing GKM protocols and identify their applicability to WMNs. Based on the review, we propose a framework for scalable and efficient GKM in WMNs, and a GKM protocol named CCoKA (Centralized COntributory Key Agreement) for use in a WMN. CCoKA is based on the scalable and efficient key tree approach and the well-known Diffie-Hellman cryptographic protocol. The proposed framework and CCoKA protocol take into account the characteristics of mesh network operations, wireless routers and mobile devices. We also suggest directions for future research on GKM in WMNs.
