无线Mesh网络安全路由

Secure Routing in Wireless Mesh Networks

Jaydip Sen

摘要:

无线网状网络(WMNs)已成为一个很有前途的概念,可以应对下一代网络中的挑战,例如提供灵活、自适应和可重新配置的架构,同时为服务提供商提供具有成本效益的解决方案。与传统的Wi-Fi网络不同,每个接入点(AP)都连接到有线网络,在WMN中,仅需要AP的子集连接到有线网络。连接到有线网络的AP称为互联网网关(IGW),而没有有线连接的AP称为网状路由器(MR)。MR使用多跳通信连接到IGW。IGW提供对传统客户端的访问,并将自组织、传感器、蜂窝和其他网络互连到因特网。然而,大多数现有的无线网状网路由协议的扩展协议最初设计的移动自组织网络(MANDO),因此,他们执行次优。此外,大多数无线网状网路由协议的设计没有考虑到安全问题,其中的节点都被假定为是诚实的。在实际部署场景中,这种假设并不成立。本章提供了一个全面的概述,在无线网状网的安全问题,然后特别侧重于在这些网络中的安全路由。首先,它识别媒体访问控制(MAC)和网络层的安全漏洞。还讨论了危及数据机密性、数据完整性、重放攻击和离线密码分析的各种可能性。然后讨论了MAC层和网络层的各种攻击。在列举了对MAC层和网络层的各种类型的攻击之后,本章简要地讨论了针对这些攻击的一些预防机制。

英文摘要:

Wireless mesh networks (WMNs) have emerged as a promising concept to meet the challenges in next-generation networks such as providing flexible, adaptive, and reconfigurable architecture while offering cost-effective solutions to the service providers. Unlike traditional Wi-Fi networks, with each access point (AP) connected to the wired network, in WMNs only a subset of the APs are required to be connected to the wired network. The APs that are connected to the wired network are called the Internet gateways (IGWs), while the APs that do not have wired connections are called the mesh routers (MRs). The MRs are connected to the IGWs using multi-hop communication. The IGWs provide access to conventional clients and interconnect ad hoc, sensor, cellular, and other networks to the Internet. However, most of the existing routing protocols for WMNs are extensions of protocols originally designed for mobile ad hoc networks (MANETs) and thus they perform sub-optimally. Moreover, most routing protocols for WMNs are designed without security issues in mind, where the nodes are all assumed to be honest. In practical deployment scenarios, this assumption does not hold. This chapter provides a comprehensive overview of security issues in WMNs and then particularly focuses on secure routing in these networks. First, it identifies security vulnerabilities in the medium access control (MAC) and the network layers. Various possibilities of compromising data confidentiality, data integrity, replay attacks and offline cryptanalysis are also discussed. Then various types of attacks in the MAC and the network layers are discussed. After enumerating the various types of attacks on the MAC and the network layer, the chapter briefly discusses on some of the preventive mechanisms for these attacks.
