Abstract

An ultra-wide band (UWB) system, a target device and a method are disclosed. In an embodiment, the UWB system comprises a UWB transceiver configured to transmit and receive signals over a specific frequency range, and a UWB processor operably connected to the UWB to process the signals. The UWB processor being configured to broadcast parameters associated with a first authentication value, the parameters being sufficient to derive the first authentication value at a plurality of mobile devices, receive a plurality of second authentication values from the plurality of mobile devices, and receive a ranging data set for each valid second authentication value from a target secure element, the ranging data set being used to authenticate a mobile device associated with the valid second authentication value for secure communication via the UWB transceiver.
