Section 4 - Wireless SecurityWireless SecurityThis section will show you the different levels of security you can use to protect your data from intruders. TheDWA-131 offers the following types of security:• WPA2 (Wi-Fi Protected Access 2)• WPA (Wi-Fi Protected Access)• 802.1x (RADIUS)• WPA2-PSK (Pre-Shared Key)• WPA-PSK (Pre-Shared Key)What is WPA?WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (WiredEquivalent Privacy).The 2 major improvements over WEP:• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keysusing a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t beentampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard instead of TKIP.• User authentication, which is generally missing in WEP, through the extensible authentication protocol(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MACaddress, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-keyencryption system to ensure that only authorized network users can access the network.WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numericpassword between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key mustbe the exact same key entered on your wireless router or access point.WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on amore secure public key encryption system to ensure that only authorized network users can access the network.D-Link DWA-131 User Manual33
