IoT Encryption Gateway equipped with quantum encryption chip based a quantum random number and method of providing encryption communication service between IoT device using the same

摘要

The present invention relates to a method of providing a secret communication service between IoT devices using a secret gateway equipped with a quantum random number-based quantum encryption chip. When the service is executed, after device authentication between the first Bihwa gateway and the first IoT device, performing remote authentication between the first Bihwa gateway and the management server, and when the device authentication is completed, the quantum encryption chip of the first Bihwa gateway generating a secret key a, transmitting the quantum public key A to a second encryption gateway; and generating and storing the quantum encryption key by the first encryption gateway to create an encrypted communication channel with the second encryption gateway. . The present invention provides the steps of performing remote authentication between the first non-hwa gateway and the management server after device authentication between the first non-hwa gateway and the first IoT device when the service is executed, and after device authentication between the second non-hwa gateway and the second IoT device, The step of performing remote authentication between the second secret gateway and the management server, and the first IoT device collecting data and transmitting the collected data to the first secreting gateway, the first secreting gateway encrypts the received data Transmitting the data to the second encryption gateway, and receiving the encrypted data from the second encryption gateway, decrypting the data and transmitting the data to the second IoT device.
