NCRYPTION
Encrypting translates data into an unreadable format using a secret key or password. Decrypting the
data requires the same key or password that was used to encrypt it. Encryption is based on the same
passkey or Link Key that is used for Authentication. If Authentication is not enabled the key is not
available and encryption will not take place.
To enable Encryption for a service:
1. Authentication must also be enabled.
2. Right-click a service name and select
Properties from the pop-up menu to
display the Bluetooth Properties dialog box.
3. Select the Encryption option. If Authentication is not enabled it will be
automatically turned on when Encryption is selected.
4. Click the OK button to close the dialog box and apply the change.

Security for local services may be configured on an individual basis. The configuration options are:

•
Encryption
To access the security settings for a local service, in the Bluetooth Configuration Panel, from the
Local Services tab, double-click the service name. Bluetooth-enabled devices from different vendors
may handle security in a slightly different manner. Refer to the user's guide for your Bluetooth device
for additional information.

A Link Key is a unique, internally generated, access code. Link Keys are generated automatically
when devices are Paired or when Authentication is enabled. Link Keys are created by combining:
•
The Passkey.
•
The Bluetooth Device Address.
•
An internally generated random number.

Pairing allows you to avoid entering access information each time a connection is attempted. Paired
devices share a unique Link Key, which they exchange when connecting. The mate of a pair will
always appear in My Bluetooth Places, even if the mate is not turned on or is out of connection range.
Paired devices remain paired even when:
1. One of the devices is not powered up.
2. A service connection is interrupted or the service is stopped.
3. One or both devices are rebooted.
When Authentication is enabled, devices are paired the first time they attempt to connect, after a
successful passkey exchange. To pair devices
before attempting a connection:
1. In the Windows system tray, right-click the
Bluetooth icon, then choose Setup | Security
from the pop-up menu.
