Abstract: Disclosed herein is an apparatus and method for transmitting/receiving information using a wireless covert channel. The apparatus for transmitting information using a wireless covert channel includes memory in which at least one program is recorded and a processor for executing the program. The program generates a packet from each of data blocks having a predetermined size acquired by dividing data and transmits the packet through a covert channel, the packet is configured with a header and a payload, and the header may include a Start Frame Delimiter (SFD) field indicating the start point of the packet, a payload attribute field indicating whether the payload is data or a Cyclic Redundancy Check (CRC), and a payload bit inversion field indicating whether the value of the payload is inverted in units of bits.
