METHOD OF GETTING ACCESS TO A VEHICLE

The invention is a method for accessing a vehicle (20) comprising a user interface (21), wherein- in response to triggering of the user interface, a transmitter (22) starts broadcasting a signal comprising a one-time UWB MAC address enciphered with a first key (Kb) and a first UWB transmitter (23) s...

Beschreibung
Zusammenfassung:	The invention is a method for accessing a vehicle (20) comprising a user interface (21), wherein- in response to triggering of the user interface, a transmitter (22) starts broadcasting a signal comprising a one-time UWB MAC address enciphered with a first key (Kb) and a first UWB transmitter (23) starts,- upon detection of the signal, an access device (10) deciphers the UWB MAC address using the first key and starts a second UWB transmitter (13), then the second UWB transmitter establishes a UWB session with the first UWB transmitter using the one-time UWB MAC address,- then the second UWB transmitter sends to the first UWB transmitter an access request comprising an access token computed from a second key (Ka), the vehicle checks the received access token is genuine by using the second key and only in case of successful checking access to the vehicle is authorized.
