BlueTooth

Bluetooth implements confidentiality, authentication and key derivation with custom algorithms based on the SAFER+ block cipher. In Bluetooth, key generation is generally based on a Bluetooth PIN, which has to be entered into both devices. This procedure might get modified slightly, if one of the devices has a fixed PIN, which is the case e.g. for headsets or similar devices with a restricted user interface. Foremost, an initialization key or master key is generated, using the E22 algorithm.

The E0 stream cipher is used for encrypting packets, granting confidentiality and is based on a shared cryptographic secret, namely a previously generated link key or master key. Those keys, used for subsequent encryption of data sent via the air interface, hardly rely on the Bluetooth PIN, which has been entered into one or both devices.

A demonstration of this reduction has been put effort in by Y. Shaked and A. Wool in An overview of the most important vulnerabilities and the most common exploits to those vulnerabilities is presented.
