Section 4 - Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DIR-330 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)
• WEP (Wired Equivalent Privacy)
What is WEP?
WEP (Wired Equivalent Privacy) is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. WEP
provides security by encrypting data over your wireless network so that it is protected as it is transmitted from one
wireless device to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When
using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit
encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal -
using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters)
format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to
HEX for use over the network. Four keys can be defined so that you can change keys easily.

Section 4 - Security
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, ensures that the keys haven’t
been tampered with. 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-specific 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.
