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.

Abstract: Disclosed herein are a one-way data transmission apparatus, a one-way data reception apparatus, and a one-way data transmission/reception method using the apparatuses. The one-way data transmission/reception method uses a one-way data transmission apparatus and a one-way data reception apparatus, and includes receiving data from a high-security zone through a one-way path, generating tag information of the data, sending a message in which the tag information is added to the data to the one-way data reception apparatus, receiving the message from the one-way data transmission apparatus, checking the tag information of the message, and transmitting the data to a low-security zone.
