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.
