Abstract

Wireless mesh networks facilitate the development of the many group oriented applications by extending the coverage area of the group communication. Group communication in a wireless mesh network is complicated due to dynamic intermediate mesh points, access control for communications between different administrative domains, and the absence of a centralized network controller. In this study, we propose a topology-matching decentralized multi-service group key management scheme for wireless mesh networks. It allows service providers to update and deliver their group keys to valid members in a distributed manner using the identity-based encryption scheme. The analysis result indicates that the proposed scheme has advantages with regard to the rekeying cost and storage overhead for a member and a mesh point in multi-sender group communication environments. The stateless property is also achieved such that a stateless member, who could not be constantly online, can easily decrypt the rekeying messages without recording the past history of transmission.
