Group key agreement performance in wireless mesh networks

Wireless mesh networks (WMN) are a promising technology to establish big wireless networks with little costs. What we need are security mechanisms that perform well in this special kind of network. Therefore we propose the application of group key agreement (GKA) protocols, since a common encryption key in the network will remove the need for reencryptions and enables a better performance. In this paper, we contribute a new theoretic approach to measure the performance of cryptographic protocols in WMN. We demonstrate the applicability of the new approach with three selected GKA protocols that have already been investigated regarding their WMN performance in previous work.
