As wireless technology widely spreads and invites its development with changes in wireless network system which supports rapid transmission, defects in security are, however, constantly witnessed. As a result, these problems have called for the needs to strengthen the hole in the technology. Though it seems that security issues between wireless communication are solved with the adoption of IEEE 802.11i as a standard, numerous attacks targeted for vulnerability of wireless mobile are increasing these days. When accesses to wireless AP from server-based, or client-based authentication, either of them determines an authorization status for use. A number of measures to prevent external attacks or information leakages are presented through the use of authorized wireless AP. Still, both server-based and client-based authentication have not only low confidentiality to external network but low solubility to a wireless AP packet which is unauthorized. In this paper, we use MAC Address to get authentication from an AP. It searches the NDIS Intermediate Driver from the wireless network card, and then controls the packets after operating the scope of IP and PORT. After having implemented the proposed model here, we came to conclusion that it is possible to solve the drawbacks of server-based authentication in security and cost. Also it showed that the proposed model enhances solubility and scalability of client-based authentication.
