33D-Link DWA-126 User ManualSection 4 - Wireless SecurityWireless SecurityThis section will show you the different levels of security you can use to protect your data from intruders. The DWA-126 offers the following types of security:• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)• WPA (Wi-Fi Protected Access) • 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 (Wired Equivalent Privacy). The 2 major improvements over WEP: • Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered 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-specic MAC address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption 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-numeric password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must be 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 a more secure public key encryption system to ensure that only authorized network users can access the network.
