Encryption Options

Encryption Description

Open Select Open (the default) when no data packet encryption is needed over the network. Selecting this

option provides no security for data transmitted over the network.

WEP-40 (40/24) Select WEP-40 (40/24) to use 64-bit key length WEP encryption (the other 24 bits are generated

automatically). If WEP-40 (40/24) is selected, other controls appear that allow you to enter keys. If the

Use Passkey check box is selected, the user is asked to enter a pass phrase between 4 and 32

characters long on the next page. Once the profile is saved, the pass phrase is converted into a key

and the pass phrase is lost. Also, if a passkey is used only one key can be set.

If the Use Passkey check box is not selected, then the user can enter up to four hexadecimal keys on

the next page. Which key is to be entered is determined by selecting a key in the Key Index drop-down

menu. The key index chosen also selects the key used for encryption. Note that Fusion sets default

values for these keys, so that entry is not absolutely required, but remember that the keys must match

the AP.

WEP-104 (104/24) Select WEP-104 (104/24) to use a 128-bit key length WEP encryption. If WEP-104 (104/24) is

selected, other controls appear that allow you to enter keys. If the Use Passkey check box is selected,

the user is asked to enter a pass phrase between 4 and 32 characters long on the next page. Once the

profile is saved, the pass phrase is converted into a key and the pass phrase is lost. Also, if a passkey

is used only one key can be set.

If the Use Passkey check box is not selected, then the user can enter up to four hexadecimal keys on

the next page. Which key is to be entered is determined by selecting a key in the Key Index drop-down

menu. The key index chosen also selects the key used for encryption. Note that Fusion sets default

values for these keys, so that entry is not absolutely required, but remember that the keys must match

the AP.

TKIP Select TKIP for the adapter to use the Temporal Key Integrity Protocol (TKIP) encryption method. This

encryption method is available whenever the Security Mode is not set to Legacy. If the Security Mode

is set to WPA personal, then the user is asked to enter a pass phrase between 8 and 63 characters

long on the next page.

AES Select AES for the adapter to use the Advanced Encryption Standard (AES) encryption method. This

encryption method is available for many of the Security Modes. If the Security Mode selected is

“personal,” the user is asked to enter a pass phrase between 8 and 63 characters long on the next

page.
