Non-cryptographic authentication and identification in wireless networks [Security and Privacy in Emerging Wireless Networks]

摘要

Lower/physical layer characteristics have been considered as potential alternatives/complements to provide security services in wireless networks. This article provides an overview of various noncryptographic mechanisms for user authentication and device identification in wireless networks using lower/physical layer properties or information. We discuss merits and demerits of these authentication/identification schemes and the practical implementation issues. Future research on cross-layer security design concludes this article.
