The IEEE 802.11 standard is becoming the most popularand efficient network topology deployed today.Providing and ensuring the security of wirelessnetwork is essential part to its continuous growth.Goals such as confidentiality and trust imply thatevery data transmitted by each user stays known onlyto the communicating parties. Authorization of usersis also a very important aspect of network integrity.There exist mechanisms defined by the Wi-Fi ProtectedAccess (WPA) protocol that enable such functionality;however, recent attacks on such system showed thatthese mechanisms can be defied. In this Book, wepropose two new security schemes. The first employs aneural network decision engine that restricts networkaccess to mobile nodes whose physical location iswithin a threshold distance from the wireless accesspoint or the controller of the network. The secondtackles the disassociation packet security flaw bywhich a malicious attacker can disconnect all networkusers by injecting two or more false managementframes into the network. Our scheme proposes the useof digital signatures as a mean to ensure theauthenticity, integrity and validity of these frames.
