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.
