The traditional Kerberos protocol exists some limitations in achieving clock synchronization and storing key, meanwhile, it is vulnerable from password guessing attack and attacks caused by malicious software. In this paper, a new authentication scheme is proposed for wireless mesh network. By utilizing public key encryption techniques, the security of the proposed scheme is enhanced. Besides, timestamp...
We propose new authentication protocols that support fast hand-off for real-time applications such as voice over IP and audio/video conferencing in wireless mesh networks (WMNs). A client and a mesh access point (MAP) mutually authenticate each other using one-hop communications. The central authentication server is not involved during the handover process. Fast authentication for roaming from one...
We aim at extending IEEE 802.11s standards to implement fast hand-off to support real-time applications such as VoIP and audio/video conferencing. We propose a novel trust model that represents the trust relationships among the entities of a wireless mesh network (WMN), and new authentication protocols based on that model. A client and a mesh access point (MAP) mutually authenticate each other using...
In this paper, we propose authentication protocols for 802.11s mesh networks, which support the mesh point's fast handoff between Mesh key distributors (MKDs). The protocols consist of the initial authentication protocol (IAP) and the fast handoff authentication protocol (FHAP). Once a MP firstly accesses the 802.11s mesh networks, the initial authentication protocol will be executed, which realizes...
In this paper, we consider QoS aware mesh networks that are maintained by multiple operators and they cooperate in the provision of networking services to the mesh clients. In order to support mobile users and seamless handover between the access points, the authentication delay has to be reduced. Many proposed fast authentication schemes rely on trust models that are not appropriate in multi-operator...
In the recent years, wireless mesh network (WMN) has evolved as a new paradigm for broadband wireless Internet access. The self-configurability, open wireless infrastructure, and different management styles of WMN make them vulnerable to malicious attackers. As a first step to secure WMNs, it is critical to incorporate an authentication mechanism for mesh clients. The existing proposals are primarily...
Recently, secure group-oriented applications have grown very rapidly. In order to provide secure group communication, WMNs (Wireless Mesh Network) are required to establish a secret key which is shared with all participants. Recently, Tseng proposed an authenticated group key agreement for regarding mobile networks. This mobile network is an asymmetric wireless network which includes many low-power...
