“…Fu et al [38,44] presented a mutual authentication scheme on the basis of a combination of techniques, such as zone-based hierarchical topology structure, virtual Certification Authority (CA), offline CA, identity-based cryptosystem, and multi-signature. By applying these techniques, the proposed scheme succeeds in improving key management in security, expandability, validity, fault tolerance, and usability.…”

Wireless Mesh Networks are considered as a promising solution for offering low‐cost access to broadband services. However, one of the main challenges in the design of these networks is their vulnerability to security attacks. In this paper, we analyze the fundamental security challenges and constraints of these networks, classify several possible attacks, and survey several intrusion prevention, detection, and response mechanisms found in the literature.

“…The authors of Reference 23 define a new authentication technique for hierarchical WMNs based on threshold cryptography, where the certification authority services are provided through the collaboration of a pre‐determined set of mesh routers. The proposed architecture extends the Diffie–Hellman key exchange protocol for negotiating a key that authorizes a user to access the backbone network services provided by a mesh router situated in a different zone.…”

Wireless Mesh Networks (WMNs) have emerged recently as a technology for next-generation wireless networking. They consist of mesh routers and clients, where mesh routers are almost static and form the backbone of WMNs. WMNs provide network access for both mesh and conventional clients.In this paper, we propose DSA-Mesh, a fully distributed security architecture that provides access control for mesh routers as well as a key distribution scheme that supports layer-2 encryption to ensure security and data confidentiality of all communications that occur in the backbone of the WMN.DSA-Mesh exploits the routing capabilities of mesh routers: after connecting to the access network as generic wireless clients, new mesh routers authenticate to a key management service (consisting of several servers) implemented using threshold cryptography, and obtain a temporary key that is used both to prove their credentials to neighbor nodes and to encrypt all the traffic transmitted on wireless backbone links.A key feature in the design of DSA-Mesh is its independence from the underlying wireless technology used by network nodes to form the backbone. Furthermore, DSA-Mesh enables seamless mobility of mesh routers. Since it is completely distributed, DSA-Mesh permits to deploy automatically and incrementally large WMNs, while increasing, at the same time, the robustness of the system by eliminating the single point of failure typical of centralized architectures.DSA-Mesh has been implemented in Network Simulator, and extensive simulations have been performed in large-scale network scenarios, comparing it to a static key approach and to a centralized architecture where a single key server is deployed. Numerical results show that our proposed architecture considerably increases the WMN security and reliability, with a negligible impact on the network performance, thus representing an effective solution for wireless mesh networking.

“…BR ij, for all i=1(1)p and j=1(1)n i, which serve as private key generation (PKG) nodes within the region/strata/group. But [6] described this BR ij as "higher performance" routers which have almost no significance to construct the PKG. These n i backbone routers would then form a virtual CA of the ith region and manage the keys using the (x i , n i )-threshold cryptographic method [8].…”

Wireless Mesh Network (WMN) is an upcoming wireless network technology and is mainly used to provide broadband internet in remote locations. It is characterized by minimum fixed infrastructure requirement and is operated in an open medium, such that any user within the range covered by mesh routers may access the network. So a critical requirement for the security in WMN is the authentication of users. However, WMN is far from mature for large-scale deployment in some applications due to the lack of the satisfactory guarantees on security. A wellperformed security framework for WMN will contribute to network survivability and strongly support the network growth or reduction. A key management model to overcome the scalability issue on security aspect for large-scale deployment of WMN i.e. Worldwide WMN is proposed in this work, which aims to guarantee wellperformed key management services and protection from potential attacks. Here, we use a combination of techniques, such as zonebased topology structure, off-line CA, virtual certification authority ) etc.
