Section 4 - Security

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.
