Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of an electronic device for performing ranging by using an ultra-wideband (UWB) in a wireless communication system, the method comprising: receiving a first ranging frame (RFRAME) from a second electronic device; receiving a second RFRAME from the second electronic device; obtaining a first ranging result based on a first single-sided two-way ranging (SS-TWR) using the first RFRAME and a second ranging result based on a second SS-TWR using the second RFRAME; and perform integrity checking, based on a result of comparing the first ranging result and the second ranging result. 2. The method of claim 1 , wherein: the first ranging result is obtained by measuring of round-trip delay of the first RFRAME, and the second ranging result is obtained by measuring of round-trip delay of the second RFRAME. 3. The method of claim 1 , wherein performing the integrity checking comprises: determining that an attack is made, based on a difference between the first ranging result and the second ranging result being greater than or equal to a threshold value; and determining that the integrity checking is passed, based on the difference between the first ranging result and the second ranging result being less than the threshold value. 4. An electronic device for performing ranging by using an ultra-wideband (UWB) in a wireless communication system, the electronic device comprising: a communicator configured to receive a first ranging frame (RFRAME) and a second RFRAME for ranging from a second electronic device; and at least one processor configured to: obtain a first ranging result based on a first single-sided two-way ranging (SS-TWR) using the first RFRAME and a second ranging result based on a second SS-TWR using the second RFRAME, and perform integrity checking, based on a result of comparing the first ranging result and the second ranging result. 5. The electronic device of claim 4 , wherein: the first ranging result is obtained by measuring of round-trip delay of the first RFRAME, and the second ranging result is obtained by measuring of round-trip delay of the second RFRAME. 6. The electronic device of claim 4 , wherein the at least one processor configured to: determine that an attack is made, based on a difference between the first ranging result and the second ranging result being greater than or equal to a threshold value, and determine that the integrity checking is passed, based on the difference between the first ranging result and the second ranging result being less than the threshold value.
