Design and Implementation of a Secure Access System to Information Resources for IEEE802.11 Wireless Networks

Information security has been one of the most sensible issues when designing communications systems; especially when this information is cataloged as confidential. This paper deals with a secure system that let you get access to privileged data, when the medium access is a wireless network based on IEEE 802.11 standard. The system designed is conformed by three main functions, which capture the first http request and forward it to an authentication server; the server validates the user´s identity in order to give access to the information resources. The control access entity determines which users are allowed or denied from the system. These functions are performed by a captive portal, an authentication server and an access point
