An electronic device, in disclosed embodiments, includes an antenna, transceiver circuitry coupled to the antenna, a memory configured to store a first operation key and instructions, and a processor coupled to the transceiver and to the memory. The processor is configured to execute the instructions stored in the memory to cause the electronic device to, in response to receiving a first transmission containing an encrypted version of a second operation key that is encrypted by the first operation key, decrypt the encrypted version of the second operation key using the first operation key to recover the second operation key, store the second operation key in the memory, transmitting, by a transmitter of the electronic device, a second transmission that contains the first operation key and a command.

A delivery assistance device assists in an operation of a delivery service in which a vehicle cabin including a trunk of a vehicle used by a requester is able to be designated as a luggage delivery destination. The delivery assistance device includes a key information distribution unit configured to distribute key information that a deliverer of a company that provides the delivery service is to use to unlock a door for access to the vehicle cabin of the vehicle, to the company, and an entry authority information distribution unit configured to distribute entry authority information regarding an authority for the deliverer to enter a predetermined area in which the vehicle is present, to the company when the key information is distributed to the company by the key information distribution unit.

A method for access management of the vehicle providing a vehicle and authenticating a user in relation to the vehicle by a proof of identity of the user. The method includes providing a cryptographically secured authorization file for the vehicle containing information relating to usage rights of the authenticated user to the vehicle to increase security in the entity-related enabling of vehicle functions.

An authentication device including: a processor; a first communication section installed at a vehicle and configured to perform first wireless communication with a terminal; and a plurality of second communication sections installed at the vehicle and configured to perform second wireless communication with the terminal, the processor being configured to: compute a distance and an angle of a position of the terminal with respect to the first communication section based on the first wireless communication of the first communication section with the terminal; cause a second communication section that, out of the plurality of second communication sections, corresponds to the computed angle, to execute the second wireless communication with the terminal; and determine, based on the executed second wireless communication and the computed distance, whether or not the terminal is present in an area corresponding to the second communication section executing the second wireless communication.

Systems and methods for performing a vehicle operation. One system includes a plurality of transceivers associated with a vehicle and a vehicle access system. The vehicle access system is configured to receive, via each of the plurality of transceivers, signal strength data associated with a portable communication device using a Bluetooth signal received at an antenna associated with each of the plurality of transceivers, and compare, for each of the plurality of transceivers, the signal strength data with a threshold signal strength value to perform a localization of the portable communication device generating the Bluetooth signal to determine whether the portable communication device is located inside or outside the vehicle. The vehicle access system is also configured to perform the operation based on whether the portable communication device is located inside or outside the vehicle.

A method for authenticating a connection between a user device and a vehicle includes sending, by the vehicle, a first wireless signal through a connection channel, receiving, by the vehicle, a second wireless signal through the connection channel, and acquiring, by the vehicle, a second signal strength sequence from second N continuous signal strength characteristics (PF.sub.Veh) of the second wireless signal, receiving, by the user device from the vehicle, the first wireless signal, acquiring a first signal strength sequence from first N continuous signal strength characteristics (PF.sub.UDev) of the first wireless signal, and communicating, by the user device, the first signal strength sequence to the vehicle.

During operation, an electronic device may provide, to a second electronic device, an invitation to share a digital car key associated with a user of the electronic device and a vehicle, where the invitation includes information for creating another instance of the digital car key on the second electronic device. Then, the electronic device may receive, from the second electronic device, a message accepting the invitation, where the message includes a certificate associated with the other instance of the digital car key on the second electronic device. Moreover, the electronic device may provide, to the second electronic device, an approved version of the certificate with a digital signature of the user. Next, the electronic device may provide, to the computer, an instruction to share the digital car key with a set of electronic devices, which is associated with a second user of the second electronic device.

A system for includes master and sniffer devices. The master device includes: first antennas with different polarized axes; a transmitter transmitting a challenge signal via the first antennas from the vehicle to a slave device, where the slave device is a portable access device; and a receiver receiving a response signal in response to the challenge signal from the slave device. The sniffer device includes: second antennas with different polarized axes; and a receiver receiving, via the second antennas, the challenge signal from the transmitter and the response signal from the slave device. The sniffer device measures when the challenge signal and the response signal arrive at the sniffer device to provide arrival times. The master or sniffer device estimates at least one of a distance from the vehicle to the slave device or a location of the slave device relative to the vehicle based on the arrival times.

The disclosure relates to the field of vehicles, and particularly, to a method and system for vehicle anti-theft authentication, a storage medium, and a vehicle including the system. The method includes the following steps: determining whether key information in a vehicle key matches preset information; performing primary anti-theft authentication between a vehicle body controller and a gateway in a case of matching, to determine whether to activate a vehicle basic function; and performing secondary anti-theft authentication between the gateway and a power controller in a case of meeting a preset condition, to determine whether to activate a vehicle driving function, where the preset condition includes that the vehicle basic function has been activated.

A vehicle information display system includes a digital license plate attachable to a vehicle and having a display able to present electronically readable visual information. This electronically readable visual information is usable to facilitate provision of services, including but not limited to vehicle rental or providing vehicle access to authorized service providers.
