Bluetooth Security
 Authorization (whether device X is allowed to have
access service Y)
• Trusted Device: The device has been previously
authenticated, a link key is stored and the device is
marked as “trusted” in the Device Database.
• Untrusted Device: The device has been previously
authenticated, link key is stored but the device is not
marked as “trusted” in the Device Database
• Unknown Device: No security information is
available for this device. This is also an untrusted
22
device.
Bluetooth Security
Bluetooth provides security between any two Bluetooth
devices for user protection and secrecy
 mutual and unidirectional authentication
 encrypts data between two devices
 Session key generation
• configurable encryption key length
• keys can be changed at any time during a connection
