In wireless mesh networks, during handoff process, the mobile client needs to authenticate with other nodes. It is necessary to ensure secure communication between the mobile client and mesh nodes. However, using the conventional public key infrastructure requires a large overhead of storage requirement, since it has to deal with the management of the public key certifications. In the present paper, an ID-based signcryption authentication algorithm for intra- and inter-domain handoff has been proposed. In this solution, a proxy-based hierarchical network has been considered. To reduce the handoff latency, a caching-list-based pre-fetching technique has been applied. During inter-domain handoff, authentication messages are encrypted using ID signcryption and signed by the mesh clients. Thus, the proposed algorithm ensures high security along with fast handoff. It has been observed from simulation results that the proposed algorithm reduces the percentage of compromised nodes, authentication delay, and communication cost with increased packet delivery ratio.

用于无线网状网络中域内和域间切换的基于 ID 的签密认证算法

在无线网状网络中，在切换过程中，移动客户端需要与其他节点进行身份验证。有必要确保移动客户端和网格节点之间的安全通信。然而，使用传统的公钥基础设施需要大量的存储开销，因为它必须处理公钥认证的管理。在本文中，提出了一种用于域内和域间切换的基于ID的签密认证算法。在该解决方案中，已经考虑了基于代理的分层网络。为了减少切换延迟，已经应用了基于缓存列表的预取技术。在域间切换期间，身份验证消息使用 ID 签密进行加密并由网格客户端签名。因此，所提出的算法确保了高安全性以及快速切换。从仿真结果可以看出，所提出的算法降低了受感染节点的百分比、认证延迟和通信成本，同时增加了数据包交付率。
