An authentication system includes a first controller that performs wireless communication with a mobile terminal and a first authentication unit that executes authentication of the mobile terminal including ID authentication and code authentication through the wireless communication performed between the first controller and the mobile terminal. The first authentication unit executes the code authentication by determining whether a terminal-side calculation result obtained by the mobile terminal matches a controller-side calculation result obtained by the first controller. The authentication system further includes a second controller that communicates with the mobile terminal and a second authentication unit that applies encryption communication using a portion of the terminal-side calculation result and a portion of the controller-side calculation result to communication performed between the second controller and the mobile terminal and authenticates the encryption communication.

Devices, methods, and a computer program for releasing transportation vehicle components and a vehicle-to-vehicle communication module. The device for releasing a vehicle component of a transportation vehicle includes at least one interface for communication with further vehicle components of the transportation vehicle and a control module for controlling the at least one interface to receive messages from the further vehicle components of the transportation vehicle and to verify the identity of the further vehicle components based on the received messages and the stored identification data of the further vehicle components. The messages on which the verification of the identity of the further vehicle components is based are messages used in regular operation of the vehicle component. The control module also releases the vehicle component in response to the identity of the further transportation vehicle components being consistent with the stored identification data of the further vehicle components.

The invention relates to a passive entry passive start system and method, and a vehicle. The system includes a vehicle and a mobile terminal, where the vehicle includes: a plurality of sensors configured to interact with the mobile terminal to acquire service-related data, each sensor having a master-slave integration function in which the sensor is able to be a master node or a slave node; a central module configured to perform data exchange with the sensors, and generate a corresponding control instruction based on the service-related data received from the sensors, and configured to designate one sensor in the plurality of sensors as a master node and the other sensors and the central module as slave nodes, or designate the central module itself as a master node and the plurality of sensors as slave nodes, where the master node implements data exchange with the slave nodes; and a controller configured to receive the control instruction from the central module and execute a corresponding control action according to the control instruction. According to the invention, separation between hardware and software can be implemented, and development flexibility can be enhanced.

A method for pairing a key fob with a control unit is provided. The key fob executes an ID authenticated key agreement protocol with a pairing device based on a key fob identification to authenticate one another and to generate a first encryption key. The pairing device encrypts a control unit identification using the first encryption key. The key fob receives the encrypted control unit identification transmitted from the pairing device. The key fob then executes an ID authenticated key agreement protocol with the control unit based on the control unit identification to authenticate one another and to generate a second encryption key. The key fob then receives an operational key transmitted from the control unit that is encrypted with the second encryption key.

An access system for a vehicle includes a receiver and an access module. The receiver is configured to receive a signal transmitted from a portable access device to the vehicle. The access module is configured to: generate a differentiated signal based on the received signal; up-sample the differentiated signal to generate a first up-sampled signal; obtain or generate an expected signal; up-sample the expected signal to generate a second up-sampled signal; cross-correlate the first up-sampled signal and the second up-sampled signal to generate a cross-correlation signal; based on the cross-correlation signal, determine a phase difference between the first up-sampled signal and the second up-sampled signal; determine a round trip time of the signal received by the receiver; and permit access to the vehicle based on the round trip time.

A method of transmitting signals from a first node having multiple transceivers to a second node is disclosed. The method comprises receiving a message from the second node at the first node, wherein the message is received by each of a plurality of transceivers of the first node; and transmitting by each of the plurality of transceivers a respective data frame to the second node in response to the message; wherein each transceiver initiates the transmission of its respective data frame a predetermined time period after receipt of the message by the transceiver; and wherein the transmissions of the data frames from the plurality of transceivers overlap. The data frames may form part of a two-way ranging exchange.

In general, aspects of this disclosure are directed towards techniques for using a computing device to perform the functionality of a vehicle key, so that the computing device may be used to automatically unlock the doors of a vehicle and/or to activate a previously-deactivated keyless ignition system. The computing device may be associated with a vehicle, including sending an identifier associated with the computing device to the vehicle via short-range communication. The computing device may also send to the vehicle, via short-range communication, at least one unlock door signal including an access code verifiable by the vehicle, and wherein receipt of the at least one unlock door signal by the vehicle enables the vehicle to unlock one or more of its doors without further user intervention.

The invention relates to an electronics unit (11) to be fit in a vehicle (10) and designed to control a functionality of the vehicle (10) upon receipt of a request from a user terminal (20), characterized in that same comprises:—a memory unit designed to store a counter and data representing a duration;—means for periodically modifying the value of the counter, the period of time being equal to said duration;—control means for controlling said functionality only when the counter is within a given range of values. Also disclosed are a method carried out in an electronics unit of said type, a method for sharing a time frame between a server and an electronics unit, and a method for synchronizing a server and an electronics unit.

A method for transferring shipments in vehicles, including: a first communications module (M1) for establishing a communication connection to a communications terminal of a supplier which receives authorization data via a communication network (N1); a first identification routine for clearly identifying a supplier; a second communication module (M2) for establishing a communication connection via a wireless communication network (N2) to a communication device of a control device of the access assembly of a vehicle; a second identification routine for clearly identifying the system by the access assembly; a third communication module (M3) for receiving update request information from the driver; and an update routine for updating authorization data in a memory of the system.

The present disclosure is directed to an automotive computer in communication with a mobile device using an authentication manager to increase and/or reduce user privileges that determine a level of vehicle control or feature access that is granted to the user. The authentication manager may increase or decrease the user privilege to standard rider status until the authentication manager has confirmed elevated status for that user via a cloud security challenge question or via a local identification method such as using the mobile device authentication features. This process may be additionally triggered based on environmental or context-based use cases, such as a high traffic condition, local cyber-attack, or transportation of sensitive goods. The system may utilize the authentication to perform out of band pairing of the mobile device and the vehicle, which may add additional security.
