Abstract: Disclosed are an apparatus and a method for Internet of Things (IoT) device security. The method includes unifying a port in a first IoT device for communication, receiving, by the first IoT device, a packet from a second IoT device through the port, identifying whether the packet in the first IoT device is in a preset packet form, verifying content of the packet in the first IoT device when the packet is in the preset packet form, and opening the port for providing a service in the first IoT device when the verifying of the packet content is successful.

Abstract: A communication method and an IoT device in a multi-MAC (Media Access Control)-operating environment. The communication method in the multi-MAC-operating environment, including synchronous MAC and asynchronous MAC, includes periodically transmitting, by the IoT device included in the multi-MAC-operating environment, a first message to a first device; determining, by the IoT device, whether to transmit a second message; transmitting, by the IoT device, a preamble packet to a second device, to which the second message is to be transmitted, when the second message is determined to be transmitted; and transmitting, by the IoT device, the second message to the second device.

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.
