Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders. The router oers
the following types of security:
• Latest Wi-Fi security with 128-bit encryption. • 802.11 128-bit AES
• 802.11 128-bit AES-PSK (Pre-Shared Key)
What is 802.11 128-bit AES?
802.11 128-bit AES , 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. 802.11 128-bit AES 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-specic MAC address, which is relatively
simple to be snied 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.
802.11 128-bit AES-PSK and the latest Wi-Fi security with 128-bit encryption 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.
802.11 128-bit AES 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.
