    摘要： Provided are an electronic device that performs ranging by using an ultra wide band (UWB) communication scheme and an operation method of the electronic device. The operation method of the first electronic device includes transmitting a first ranging control message (RCM) comprising interval information to a second electronic device, determining a time point to transmit a second RCM based on the interval information, determining a range of a first RCM timing window, based on the determined time point, transmitting the second RCM to the second electronic device in the first RCM timing window, and transmitting a third RCM at a random time point in a second RCM timing window, when a response message with respect to the transmitting of the second RCM is not received in a preset range.

    摘要： Provided is a method, performed by an electronic device, of communicating with another electronic device through first communication, the method including: generating a first key based on a secret key of the electronic device and a public key of the other electronic device received through second communication independent of the first communication; transmitting a public key of the electronic device to the other electronic device through the second communication such that a second key corresponding to the first key is generated at the other electronic device; generating a timestamp sequence based on the first key; and conducting communication with the other electronic device through the first communication by using the timestamp sequence.
