Wireless Security

This section will show you the dierent levels of security you can use to help protect your data from intruders. The DWR-953V2 oers

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 (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. WPA2 is based on 802.11i and uses Advanced Encryption Standard

(AES) 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 snied out and stolen. EAP is built on a stronger public-key encryption system so that only authorized network

users should be able to 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. This is the technique typically used on home networks.

WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on an even stronger key

encryption system to make it much more dicult for unauthorized network users to access the network. EAP is often used in corporate

or university environments.
