1. A method, performed by a first electronic device, of wireless communicating with a second electronic device using a first communication protocol, the method comprising:
receiving, from the second electronic device, a public key of the second electronic device using a second communication protocol;
generating a first key based on a secret key of the first electronic device and the public key of the second electronic device;
transmitting a public key of the first electronic device to the second electronic device;
generating three parameters based on the first key and an additional information, wherein the three parameters include STSkey (phyHarpUwbStsKey), Vupper (phyHrpUwbStsVUpper96) and counter ((phyHrpUwbStsVCounter);
generating a scrambled timestamp sequence (STS) based on the three parameters; and
communicating with the second electronic device through the first communication protocol by using the STS,
wherein the first communication protocol is independent of the second communication protocol, and
wherein the additional information includes at least one of identification information of the first electronic device, a nonce generated by the first electronic device, and a nonce generated by a security element of the first electronic device.
