An anonymous batch handover authentication protocol for big flow wireless mesh networks

Wireless mesh network (WMN), as a new generation of wireless network technology, has raised increasing concerns in recent years. Due to the strong mobility nature of the clients in WMNs, the handover events frequently occur. Therefore, taking into consideration the openness of the wireless communication channel, the handover authentication protocols for WMNs have to be both efficient and secure, which remains a challenge. In this paper, an anonymous batch handover authentication protocol is proposed using group signature technique to pre-distribute handover keys. Unlike existing protocols based on group signature, the proposed protocol does not involve group signature correlation operations in the handover authentication phase, hence achieving a better performance.
