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.
