Wireless security techniques

Abstract

This paper provides a survey of the different techniques that can be used to strengthen security in wireless local area networks (WLANs). The first generation of WLANs were deployed by small businesses and individuals at homes. The second generation of WLAN products are more secure than those of the first generation. Second generation broadband wireless networks are considered to be enterprise-level networks providing more capacity and coverage than first generation home-and small business-based WLANs. However, security remains the most critical area of concern in both first generation and second generation WLANs. In this paper, we provide a survey of second generation broadband WLANs technologies and focus on security techniques.

Framework for Wireless Network Security Using Quantum Cryptography

“…Besides standard and conventional methods of security services to users some of the other effective ways to secure WLANs are as follows [13]:…”

A mobile IP based WLAN security management framework with reconfigurable hardware acceleration

“…One or more wireless Access Points (AP), a Wireless Policy Zone Controller (WPZCon) and a Local Role Server (LRS) separated from other zones by a zone router together comprises a Wireless Policy Zone. The authentication of the users and the access points are managed by a special authentication server (AS) called Central Authentication & Role Server (CARS) which can be a RADIUS or an AAA server [11]. It also assigns appropriate roles to the authenticated users based on user credentials and policy zone (location) information.…”

“…In this paper, we propose a wireless security policy management framework supported by a spatio-temporal RBAC model and a SAT based verification. The novelty of the work lies in • The use of mobile IP to model the wireless nodes increases the performance of the system and gives better results compared to MAC based models as referred in [11] and [14].…”

A Formal Verification Framework for Security Policy Management in Mobile IP Based WLAN

“…The authentication of the users and the access points are managed by a special authentication server (AS) called Central Authentication & Role Server (CARS) which can be a RADIUS or an AAA server [16]. It also assigns appropriate roles to the authenticated users based on user credentials and policy zone (location) information.…”
