Random number based authentication for heterogeneous networks

Abstract

To deal with the increasing demand for heterogeneity, a new authentication protocol have been proposed to increase the efficiency of interworking wireless security; they enable mutual authentication among users in inter and intra domain networks. However, to expand inequitable distribution of heterogeneous networks, an intruder may impersonate a legitimate user's signal. Therefore, a secure legitimate user detection method that can distinguish an allowed user's gesture from an attacker's gesture is needed. To generate a trust relationship between user, base station and home network, a novel approach for authenticating protocol which kowtow heterogeneity requirements. It integrates cryptographic credentials, public/private key of base station, random number challenges to facilitate user detection in the presence of intruders. The random number serves as an association, to enable a home network to verify equivalent certificate carried by the base station per user's request. A key involvement in this paper is a new physical layer authentication technique that enables the base station authentication signals from its associated users.
