Abstract:
1. A method for secure pairing of two or more ultra-wideband (UWB) devices, comprising: initiating device discovery with at least a first UWB device by entering a low power UWB transmit mode for the first UWB device and transmitting a beacon signal from the first UWB device for device discovery; conducting automatically secure pairing between the first UWB device and a second UWB device over in-band UWB communications; to automatically generate one or more pairing secrets for subsequent UWB communications between the first and second UWB devices using a key exchange protocol based upon device-known or device-generated information to generate the one or more pairing secrets; wherein the conducting and generating steps are conducted without requiring a visual match confirmation through graphical user interfaces (GUIs) of the first and second UWB devices.
