Abstract: A method and apparatus for generating a secret key includes: acquiring a random sequence by use of reciprocity of a radio channel; generating the secret key based on the random sequence; and stopping generating the secret key when it is determined that the radio channel is flat based on flatness measured from the radio channel.

Abstract: Disclosed herein are a method of performing synchronization in a distributed wireless communication system, and a terminal supporting the same. A distributed wireless communication system includes a plurality of networks. Time resources of each of a plurality of networks are divided into a synchronization slot, a discovery slot, a peering slot, and a data slot. A first terminal belonging to a first network determines whether a synchronization signal is received from a terminal belonging to a second network in the data slot of the first network. The first terminal detects whether it has met the second network that is out of synchronization with the first network if the synchronization signal is determined to have been received.

Abstract: A terminal and method for recognizing a communication target within a visible range. The method of a terminal to recognize a communication target includes obtaining location information of a communication target whose identification information is unknown within a visible range of a terminal user; and recognizing a relative location of the communication target with respect to the terminal based on the obtained location information and displaying the recognized relative location of the communication target.
