CHAPTER 24: Configuring WEP and WPA Encryption

WEP Encryption Settings

Open-systemauthentication is the only method required by 802.11b. In open-system authentication, the SonicWALL allows the wireless client access without verifying its identity.

Shared-keyauthentication uses WEP and requires a shared key to be distributed to wireless clients before authentication is allowed.

The TZ 50 Wireless/TZ 150 Wireless/TZ 170 Wireless provides the option of using Open System, Shared Key, or both when WEP is used to encrypt data.

If Both Open System & Shared Key is selected, the Default Key assignments are not important as long as the identical keys are used each field. If Shared Key is selected, then the key assignment is important.

To configure WEP on the SonicWALL, log into the SonicWALL and click Wireless, then WEP Encryption.

1Select the authentication type from the Authentication Type list. Both (Open System & Shared Key) is selected by default.

2Select 64-bit or 128-bit from the WEP Key Mode. 128-bit is considered more secure than 64-bit. This value is applied to all keys.

WEP Encryption Keys

1Select the key number, 1,2,3, or 4, from the Default Key menu.

2Select the key type to be either Alphanumeric or Hexadecimal.

WEP - 64-bit		WEP - 128-bit
Alphanumeric - 5 characters (0-9, A-Z)		Alphanumeric - 13 characters (0-9, A-Z)
Hexadecimal - 10 characters (0-9, A-F)		Hexadecimal - 26 characters (0-9, A-F)
3	Type your keys into each field.
4	Click Apply.

WPA Encryption Settings

WPA supports two protocols for storing and generating keys:

•Extensible Authentication Protocol (EAP): EAP allows WPA to synchronize keys with an external RADIUS server. The keys are updated periodically based on time or number of packets. Use EAP in larger, enterprise-like deployments where you have an existing RADIUS framework.

•Pre-Shared Key (PSK): PSK allows WPA to generate keys from a pre-shared passphrase that you configure. The keys are updated periodically based on time or number of packets. Use PSK in smaller deployments where you do not have a RADIUS server.

Note: WPA support is only available in Access Point Mode. WPA support is not available in BridgeMode.
