3Com WL-455 manual WPA Configuration, Configuring Encryption

Page 44

CONFIGURING ENCRYPTION

There are two types of data encryption available:

•WPA—Wi-Fi Protected Access.

•WEP—Wired Equivalent Privacy.

The access point and the wireless devices must have the same encryption settings

to communicate. You can choose to allow only clients using WPA encryption, or you can allow both WPA and WEP clients.

The following sections describe how to configure each type of encryption. When you are finished configuring the encryption, click Apply.

WPA Configuration

To configure WPA encryption:

1Under WPA Configuration, click the Required check box if you want to limit access to clients using WPA encryption. If you also want to allow WEP clients, do not check this box.

2Select the Cipher Mode, which determines the method by which keys are computed. WEP is the weakest Multicast Cipher Mode and is only provided for support of legacy clients which do not fully support WPA. Clients associated with WPA-TKIP will have unicast packets directed at them with corresponding encryption keys. However, with WEP selected as the Cipher Mode, ALL multicast traffic is sent out with WEP encryption. It is recommended to only select WEP as the Cipher Mode if legacy client support is critical.

AES - Advanced Encryption Standard (Highest Security)

TKIP—(Temporal Key Integrity Protocol) provides per-packet key mixing, a message integrity check and a re-keying mechanism

WEP—Provides standard WEP ciphering (Least Secure)

3Select the type of WPA Key Management:

WPA authentication over 802.1x (More secure, but requires a RADIUS authentication server setup. (See WPA note below)

WPA Pre-shared Key (PSK) (see WPA note below)

4Select the Key Type:

Hexadecimal (0~9, A~F; for example, D7 0A 9C 7F E5) Alphanumeric (0~9, A~F; for example 01234)

5Enter the pre-shared key in the space provided if necessary.
