Securing multi‐operator‐based QoS‐aware mesh networks: requirements and design options

Abstract

AbstractWireless mesh networking allows network operators and service providers to offer nearly ubiquitous broadband access at a low cost to customers. In this paper, we focus on QoS‐aware mesh networks operated by multiple operators in a cooperative manner. In particular, we identify the general security requirements of such networks and we give an overview on the available design options for a security architecture aiming at satisfying those requirements. More specifically, we consider the problems of mesh client authentication and access control, protection of wireless communications, securing the routing, key management, and intrusion and misbehavior detection and recovery. Our aim is to structure this rich problem domain and to prepare the grounds for the design of a practically usable security architecture. Copyright © 2008 John Wiley & Sons, Ltd.
