摘要： Provided is a ranging method capable of perform integrity checking when ranging is performed using an ultra-wideband (UWB). A method for performing ranging by an electronic device using an ultra-wideband, 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.

摘要： In accordance with a first aspect of the present disclosure, an attack detection method is conceived, comprising: performing ranging operations between at least two ultra-wideband (UWB) nodes comprised in a communication network, wherein said ranging operations output ranging results; performing at least one consistency check on the ranging results output by the ranging operations; detecting at least one attack on an estimated distance between one or more of said UWB nodes using an output of the consistency check. In accordance with further aspects of the present disclosure, a corresponding attack detection system is provided, as well as a computer program for carrying out the attack detection method.
