The operation of achieving authenticated key agreement between two human-operated mobile devices over a short range wireless communication channel, such as bluetooth or Wi-Fi, is known as \"Pairing\". The devices being paired are ad hoc in nature, i.e., they cannot be assumed to have a prior context (such as pre-shared secrets) or a common trusted on- or off-line authority. However, the devices can generally be connected using auxiliary physical channel(s) (such as audio or visual) that can be authenticated by the user(s) of the devices. These authenticatable channels can thus be used to form a basis for pairing.
