Wireless Networks based on WIFI or WIMAX become popular and are used in many places as compliment network to wired LAN to support mobility. There is performance issues associated with the usage of WLAN that put some restriction on adapting this technology everywhere. Securing the open access to avoid attacks at the physical and MAC layer with high speed performance during authentication is considered...
This paper presents the architecture of an integrated secure wireless ordering and transaction processing system. Wireless communication between the various system components is primarily done using WiFi technology. The ordering and subsequent transaction processing are done at the user end using a WiFi enabled PDA that communicates with a local server which in turn sends requests and receives confirmations...
With the increasing dependence on wireless LANs (WLANs), businesses, educational institutions and other organizations are in need of a reliable security mechanism. The latest security protocol, the IEEE 802.11i assures rigid security for WLANs with the support of IEEE 802.1x protocol for authentication, authorization and key distribution. Nevertheless, fresh security threats are emerging often to...
Security is always a key concern for network operators. They are thus always looking for effective new security tools to work with. Eight years ago, an authentication technology called IEEE 802.1X was supposed to be an important tool for local area networks. 802.1X provides a security framework by letting PCs, Internet phones, and other devices connect to a LAN only if they can authenticate themselves...
