A system and method for a distributed security model that may be used to achieve one or more of the following: authenticate system components; securely transport messages between system components; establish a secure communications channel over a constrained link; authenticate message content; authorize actions; and distribute authorizations and configuration data amongst users' system components in a device-as-a-key system.

System and method for authenticating and authorizing devices

A system and a method to wirelessly synchronize, monitor, or communicate, or a combination thereof, amongst sensors (e.g., sensors, hubs, sensor controllers, etc.) in a Bluetooth Low Energy-based microlocation system. The system or method, or both, may use the BLE hardware (e.g., transmitters, receivers, antennas, etc.) to interleave a communications protocol within the connection interval gaps of the BLE protocol used to communicate with devices.

System and method for microlocation sensor communication

A communication system with a master device configured to determine location information in real-time with respect to a portable device. The master device may direct one or more monitor devices to monitor communications that occur over a primary communication link. The monitor devices may sense characteristic information about the signal from the portable device, and communicate this characteristic information to the master device via an auxiliary communication link. The communication system may determine location of the portable device, authenticate the portable device, determine whether the portable device is authorized to allow or initiate an action, and command or enable an action with respect to equipment.

System and method for establishing real-time location

A system is provided and includes a receiver and an access module. The receiver is configured to receive a signal transmitted from a portable access device to a 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, up-sample an 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, determine, based on the cross-correlation signal, 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 based on the phase difference, and permit access to the vehicle based on the round trip time.

Up-sampling and cross-correlation for time of arrival determinations in passive entry/passive start systems

A reader includes a transceiver and a control module. The transceiver is configured to, during a current connection event, monitor notification messages transmitted from a portable access device to a phone-as-a-key (PaaK) system of a vehicle, where the notification messages are transmitted to establish a communication link between the portable access device and the PaaK system. The control module is configured to: perform an in-phase and quadrature phase capture of the notification messages based on fields in one or more of the notification messages, where the fields include a mobile de-whitened section including two or more series of consecutive bits, where the consecutive bits in each of the one or more series are all zeros or all ones; based on the in-phase and quadrature phase capture, determine an angle-of-arrival of the notification messages, and indicate the angle-of-arrival to the PaaK system for permitted access determined by the PaaK system.

Antenna switching control for AOA capturing in phone-as-a-key systems with de-whitened tone transmission, CRC based validation and event timing

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.

Passive entry/passive start access systems including round trip time sniffing

A method and system of creating microlocation zones by defining virtual boundaries using a system of one or more transmitters and receivers with one or more spatially-correlated antennas.

Method and system for establishing microlocation zones

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 portable access device for wirelessly gaining access to a vehicle includes a transceiver, receive and transmit queues, and a control module. The transceiver, during a current connection event, receives first notification messages from a PaaK system of the vehicle and in response thereto transmits second notification messages to the PaaK system. The first notification messages and the second notification message are transmitted to establish a communication link between the portable access device and the PaaK system. The receive queue receives the first notification messages. The transmit queue stores the second notification messages. The control module, based on a first one of the first notification messages, determines what data was transmitted during a last connection event prior to the current connection event and generates one or more of the second notification messages to include data not previously received during the last connection event.
