NON-CRYPTOGRAPHIC AUTHENTICATION AND IDENTIFICATION IN WIRELESS NETWORKS

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 non-cryptographic 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.
