Abstract
In a radiofrequency network, such as a Bluetooth network, two devices are securely identified to one another for a communication session. One of the devices is designated as a master apparatus, and the other is a slave apparatus. An automatic identification process is carried out by placing the two devices in close proximity with one another, and transmitting very short range signals from the master apparatus, to be exclusively received by the slave apparatus. If the two devices are able to communicate over this short range, an identification key is generated and passed to the slave apparatus for subsequent exchanges in normal, larger range communications.
