Secure ranging system

A computer-implemented method when executed by data processing hardware causes the data processing hardware to perform operations comprising:

• receiving, at a controller of a responder device, a connection request from an initiator device;
• executing, via a secure ranging application of the controller, an ultra wideband (UWB) ranging session;
• executing, via the controller, a first measurement of the initiator device relative to the responder device;
• identifying at least one verification protocol of the secure ranging application based on the executed UWB ranging session, the at least one verification protocol including at least one of a correlation-based ranging protocol, a secondary ranging protocol, a motion sensor protocol, and a dual factor protocol;
• executing, based on technology resources of the responder device, one of the correlation-based ranging protocol, the secondary ranging protocol, the motion sensor protocol, and the dual factor protocol including executing the secondary ranging protocol including:
• executing a second measurement via a measurement function of the secure ranging application;
• comparing the second measurement with the first measurement;
• and
• generating, based on the compared first measurement and second measurement, an acceptance signal;
• and
• executing, based on the at least one verification protocol, a command function at the controller of the responder device.

A secure ranging system for a vehicle, the secure ranging system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• receiving, at a controller of a responder device, a connection request from an initiator device;
• executing, via a secure ranging application of the controller, an ultra wideband (UWB) ranging session;
• executing, via the controller, a first measurement of the initiator device relative to the responder device;
• identifying at least one verification protocol of the secure ranging application based on the executed UWB ranging session, the at least one verification protocol including at least one of a correlation-based ranging protocol, a secondary ranging protocol, a motion sensor protocol, and a dual factor protocol;
• executing, based on technology resources of the responder device, one of the correlation-based ranging protocol, the secondary ranging protocol, the motion sensor protocol, and the dual factor protocol including executing the correlation-based ranging protocol including:
• executing, based on the first measurement being within a measurement range, a localization function via the secure ranging application;
• sending, based on the executed localization function, localization data including one or more of a responder identification (ID), an initiator ID, an initiator location, and a ranging time to a back office server;
• requesting, via the back office server, log ranging data from an authorized device;
• and
• comparing the localization data with the log ranging data;
• and
• executing, based on the at least one verification protocol, a command function at the controller of the responder device.
