Encryption Tab

Use the Encryption tab for configuring encryption settings. The absence of a physical connection
makes wireless links vulnerable to information theft. Encryption is an efficient method of preventing
data theft and improving data security. The firmware supports Open System and Shared Key (40-bit)
Encryption algorithms.
MicroAP Authentication Options A MicroAP can use Open System, Shared Key or both. If Shared Key
is enabled and Open System is not, the MicroAP grants access to adapters that have Shared Key
enabled and are using the correct Encryption Key algorithm.
Adapters using Open System cannot associate to the MicroAP when the MicroAP has Shared Key
enabled. Only when the MicroAP is using Open System can Open System mobile computers associate
to it.
1. Use the Encryption Algorithm drop-down list to select the adapter Encryption algorithm. The
Open System algorithm (default setting) does not encrypt packets over the network. Select
Open System to disable Encryption for the WLAN adapter and allow for the transmission and
receipt of data with no security.
2. Use the Shared Key option to enable 40-bit Encryption. Tap the Encryption key (to be used
for the mobile computer) and enter 10 hex digits for each key used. Tap OK to save and
implement the encryption key data.
3. Tap a radio button and tap Reset Keys to clear the entries in the Shared Encryption Key
fields.
