Abstract
An electronic device includes communication circuitry configured to perform short-range wireless communication, ultra-wideband (UWB) communication circuitry configured to perform UWB communication, a secure element comprising a secure data storage configured to provide an execution environment isolated from an operating system (OS) of the electronic device, and a processor. The UWB communication circuitry performs ranging with an external electronic device, receives a first UWB signal including a medium access control (MAC) header and a MAC payload from the external electronic device, and determines, based at least on MAC payload information included in the MAC payload, whether to forward information included in the MAC payload information element to the secure element.
