Secure identification method between two radiofredquency network appliances
First Claim
1. A process for secure recognition between two units (10, 12) of a radiofrequency network, characterised in that it comprises the following steps, consisting in:
- (a) switching on the two units (10, 12) (b) selecting one (10) of the two units as the master unit and the other (12) as the slave unit, (c) moving the two units (10, 12) to the immediate proximity of one another (d) launching on the master unit (10) an automatic secure recognition process consisting in;
(d1) transmitting signals according to a radiation pattern in such a way that the signals are only received by the slave unit (12), (d2) launching a standard connection process to the radiofrequency network and, in the case of successful connection to the radiofrequency network, (d3) generating a recognition key with the intention of making subsequent exchanges secure, (d4) re-transmitting signals according to the normal radiation pattern, and (e) placing the two units (10, 12) at a distance from each other for operation at a normal distance.

Abstract
The invention concerns a method for accessing radio-frequency networks known as BLUETOOTH. The access to an apparatus is obtained via a network apparatus by selecting one of the two appliances as master-apparatus (10) and the other as slave-apparatus (12), and by initialising on the master-apparatus (10) an automatic identification procedure consisting essentially in placing the appliances (10, 12) in immediate proximity and in transmitting very short range signals to be exclusively received by the slave-apparatus (12). Then it consists in initialising a standard connection procedure and if it is successful, an identification key is generated which is used for subsequent exchanges in normal operating conditions.
