A small scale Internet of things system of the present invention comprises: devices; a gateway or a sharer for allocating device IDs to two or more devices, generating communication path information by combining the device IDs, encrypting the generated communication path information, generating communication path registration information by matching each of the device IDs with the encrypted communication path information, storing the generated communication path registration information and transmitting the encrypted communication path information to corresponding devices in the event that a registration request for communication is generated from the two or more devices of the devices, and reading the communication path registration information including the encrypted communication path information in a communication request message, extracting communication path registration information including the remaining device IDs except a device ID of a device for transmitting the communication request message of the communication path registration information, and transmitting a communication admission message to devices corresponding to the device IDs included in the extracted communication path registration information and a device for requesting communication in the event that the communication request message including the device ID and the encrypted communication path information is received from any device. Here, the devices receive the encrypted communication path information and store the received encrypted communication path information, and the devices for receiving the communication admission message communicate with one another. |
