Nespot provides a convenient wireless internet connection service. The existing IEEE 802.1X EAP-MD5 authentication mechanism can be achieved based on ID/password information for a wireless connection. The Nespot system offers an advanced accounting and authorization procedure for providing wireless user authentication mechanism. However, many problems were found on the existing Nespot EAP-MD5 mechanism such as a ill value exposure, a leakage of personal information on wireless authentication procedure and a weakness on Nespot mutual authentication mechanism. Therefore, we analyzed the limitation of the existing IEEE 802.1X EAP-MD5 certification system, and suggested a one-time session key based authentication mechanism. And then we offered a simplified encryption function on the Nespot certification process for providing secure mutual authentication process.

PDA 시장이 부활조짐을 보이고 있다. 지난 1분기 PDA 내수시장은 4만대에 근접해 지난해 같은 기간보다 20% 이상 확대된 것으로 나타났다. 개인용 시장은 네스팟 물량과 내비게이션 전용단말기 수요가 시장을 견인했고, 산업용 시장도 물류와 교육 및 방문판매 등 공급선이 늘어나 전체시장 확대에 일조했다.

Currently, Wireless LAN(WLAN) service is widely deployed to provide high speed wireless Internet access through the mobile stations such as notebook and PDA. To provide enhanced security and user access control in the public WLAN area, WLAM access points should have the capability of IEEE 802.1x-based user authentication and authorization functionality. In this paper, we provide a brief understanding of IEEE 802. 1x standards and related protocols likeEAPoL(Extended Authentication Protocol Over LAN), EAP, RADIUS and describe how the IEEE 802.1x is designed and implemented in our embedded linux-based WLAN AP which is named i-WiNG.(Intelligent Wireless Internet Gateway).
