Abstract: Disclosed is a method for ultra-wide band (UWB) security ranging and a UWB device configured to perform secure ranging. The method includes obtaining, from a UWB sub-system of the UWB device, first encryption data including a symmetric key encrypted with a public key of a secure application of the UWB device; transferring the first encryption data to the secure application; obtaining, from the secure application, second encryption data including a ranging data set (RDS) encrypted with the symmetric key; and transferring the second encryption data to the UWB sub-system. In this case, the RDS may include a ranging session key configured to secure a UWB ranging session, and the secure application may be included in a trusted execution environment area.

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: A method for UWB secure ranging is disclosed. An electronic device method according to one embodiment of the present disclosure may comprise the operations of: transmitting, to a secure component, a request for setting a ranging data set for secure ranging; and transmitting, to the secure component, a request for transmitting the ranging data set to a UWB subsystem. Here, the ranging data set can be transmitted to the UWB subsystem from the secure component by using a secure channel set between the secure component and the UWB subsystem through a framework.
