Abstract: Provided is a secure ranging method capable of blocking access of a malicious user by preventing an attack by the malicious user when ranging is performed using an ultra-wideband (UWB). Also, provided is a method of increasing accuracy of ranging. A method of operating an electronic device for performing ranging by using a UWB in a wireless communication system includes: transmitting and receiving at least one frame for ranging, to and from at least one other electronic device; obtaining a first ranging value and a second ranging value, based on the at least one frame; and performing integrity checking, based on a result of comparing the first ranging value with the second ranging value.

Abstract: Provided is a method, performed by an electronic device, of performing secure ranging with a target device. The method of performing secure ranging may include receiving a connection message for communication with the target device using a first communication method through a first communicator, transmitting, by a first applet in a secure element of the electronic device, a ranging session key for the target device to a second applet in the secure element, the ranging session key being stored in the first applet, receiving a ranging session request from the target device, based on the ranging session request, obtaining, by a second communicator, the ranging session key for the target device from the second applet, and by using the ranging session key, performing secure ranging using a second communication method with the target device through the second communicator.
