Claim 17:
18. A method for managing an Internet of Things (IoT) to be performed by an IoT device management system provided with a first virtual device to an n-th virtual device where ‘n’ is a natural number greater than or equal to 2 and a virtual device management apparatus, wherein an i-th virtual device (where T is a natural number greater than or equal to 1 and less than or equal to ‘n’) among the first virtual device to the n-th virtual device includes an i-th memory region corresponding to a memory disposed in a normal zone of an i-th IoT device and an i-th computational unit connected to a driver disposed in a secure zone of the i-th IoT device through a trust network, the method comprising:
(a) receiving, by the i-th computational unit, data change information of the memory of the i-th IoT device from the driver of the i-th IoT device through the trust network, the data change information being information on changes of data in the first memory;
(b) applying, by the i-th computational unit, the data change information to the i-th memory region;
(c) generating, by the virtual device management apparatus, an instruction for an operating state of the i-th IoT device by determining whether the i-th virtual device operates normally;
(d) transmitting, by the virtual device management apparatus, the instruction for the operating state of the i-th IoT device to the i-th virtual device;
(e) receiving, by the i-th computational unit, the instruction for the operating state of the i-th IoT device from the virtual device management apparatus; and
(f) transmitting, by the i-th computational unit, the instruction for the operating state of the i-th IoT device to the driver of the i-th IoT device through the trust network.
