Abstract
Disclosed herein is an Internet of things (IoT) device which is capable of defending against an attack such as hacking while strengthening security of IoT by dynamically determining whether to operate as a master device in an IoT network, and, when the master device is determined, generating, distributing, and managing private keys of other IoT devices in the IoT network.
Claims20
A first IoT (Internet of Things) device in an IoT network of the first IoT device through an nth IoT device (where n is a natural number equal to or greater than 2), the first IoT device comprising:
- a key generator configured to store a master key and including a key generation logic for generating a private key based on the master key;
- a receiver/transmitter configured to communicate with the second IoT device through the nth IoT device in the IoT network;
- and
- a processor configured to perform:
- (a) determining whether the first IoT device is a master device in the IoT network;
- (b) when the first IoT device is determined to be the master device in the IoT network, generating a second private key through an nth private key respectively corresponding to the second IoT device through the nth IoT device by using the key generator and transmitting the second private key through the nth private key to the second IoT device through the nth IoT device, respectively, via the receiver/transmitter;
- and (c) when the first IoT device is determined to be not the master device in the IoT network, receiving a first private key corresponding to the first IoT device from one of the second IoT device through the nth IoT device determined as the master device.
