6.4 ENCRYPTION
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 in BTW 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 use Encryption, Authentication must be enabled.
To enable Encryption for a service:
1. Right-click a service name and select Properties from the pop-up menu to display
the Bluetooth Properties dialog box.
2. Select the Encryption option. If Authentication is not enabled it will be
automatically turned on when Encryption is selected.
3. Click the OK button to close the dialog box and apply the change.
6.5 LEVELS OF SECURITY
Security for local services may be configured on an individual basis.
The configuration options are:
• Startup-Automatic or Manual
• Authorization
• Authentication
• 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.
6.6 LINK KEY
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.
