Non-repudiable authentication and billing architecture for wireless mesh networks

Abstract

Wireless mesh networks (WMNs) are a kind of wireless ad hoc networks that are multi-hop where packets are forwarded from source to destination by intermediate notes as well as routers that form a kind of network infrastructure backbone. We investigate the security of the recently proposed first known secure authentication and billing architecture for WMNs which eliminates the need for bilateral roaming agreements and that for traditional home-foreign domains. We show that this architecture does not securely provide incontestable billing contrary to designer claims and furthermore it does not achieve entity authentication. We then present an enhanced scheme that achieves entity authentication and nonrepudiable billing.
