Hereinafter, a process of generating virtual objects in the virtual object server according to the present invention will be described with reference to FIG. In FIG. 2, the user terminal and the web server are functionally separated from each other only for the sake of description of the operation. In actuality, the user terminal can embody a web server so that the user can remotely control the web server through the web server. The user terminal may be implemented with a main controller for controlling peripheral devices and a display device, an input device and a network communication device as peripheral devices.

2, the user terminal transmits connection request information to a web server that remotely controls the object apparatus according to a user operation command and data input by the user (S211), and the web server sends web interface information to the user terminal (S212 ). The connection request information may include security authentication information registered in the web server and subscriber identification information (ID and password). For example, the web interface information may include an input window for requesting virtualization object creation and deletion and virtualization object data.

The web server establishes a security session to communicate with the virtualization object server, and then sends a virtualization object (VT) generation request message including virtualization object (VT) generation information to the virtualization object server in operation S215.

The virtualization object server analyzes the header area of the virtualization object (VT) creation request message and generates a new virtualization object (VT) when it is determined that the message is a request for virtualized object creation, The identification information (ID) of the new virtual object VT is generated and stored (S216). The virtualization object server analyzes the data area of the virtualization object (VT) creation request message, extracts the protocol information and the data format information used by the object device corresponding to the new virtualization object (VT), and stores the protocol information and the data format information in a storage (S217). Although not shown in FIG. 2, the virtualization object server transmits identification information (ID) of a new virtualization object (VT) to a web server that requests creation of a virtual object (VT).

A new virtualization object (VT) of the virtualized object server establishes a secure channel with the object device (S218). The method of creating a secure channel between a new virtual object (VT) and an object device depends on the protocol connecting the object device and the new virtual object (VT). For example, in the case of TCP / IP, a device connected to a network sends a connection request message to a new virtualization object (VT) using a network address of a new virtualization object (VT), and a new virtualization object The object device exchanges and confirms the authentication information and sends the mutual authentication result to each other. New virtualization objects (VT) and object devices establish a secure channel with normal end-to-end encryption with authentication information. Since the authentication information key can be used only in the secure channel, the communication between the object device and the new virtual object (VT) is performed only through the established secure channel. In order to communicate with each other, the object authentication information is required. Do.

The web interface processing unit 131 processes a message input from a web server and data input from a virtual object. For example, the web interface processing unit 131 may receive, from a header area of a message received from the web server, a method indicating a purpose of a message, identification information of a virtual object to receive data of the message, Information is extracted. If the message protocol is HTTP, the format of the request line in the message header can be implemented as "method type http: // virtualized object server domain name / virtual object identification (VT ID) / data structure language type".

The web interface processing unit 131 searches for a virtual object existing in the virtualized object resource pool 133 using the identification information (VT ID) of the virtual object, and then displays the method and message indicating the purpose of the message in the virtual object Data and information about the language that specifies the data structure of the message is transmitted. The method includes a GET method for requesting data of a virtual object, a PUSH method or a PUT method for requesting a function control signal, setting of a function parameter, or firmware update of the object apparatus.

After the virtualization object manager 132 generates the data format converter and the secure channel processor, the virtualization object manager 132 generates identification information of a new virtualization object and stores it as a virtualization object storage information as verification information for accessing the object device. That is, the web interface processing unit 131 checks the identification information (VT ID) of the virtualized object in the header area of the message transmitted from the web server and confirms whether the web server that sent the message has the right to access the virtualized object (VT) (VT) of the virtualization object is used as a key value to find the virtualized object (VT).

Virtualized object 410 included in virtualized object resource pool 133 includes virtualized object identification information 411, object device data format information 412, object device protocol information 413, A virtualization object repository and a data format converter 415 for storing device authentication information 414, and a secure channel processor 416.

The data format converter 415 converts the data input from the web interface processing unit 131 according to the object device data format information 412. For example, when the data format converter 415 receives a method indicating a purpose of a message, data of the message, and information on a language that specifies the data structure of the message, the data format converter 415 receives the data structure of the message The metadata and the actual data are classified according to the specified language and the method and the data of the message are checked to classify the purpose of the data and the function item and the function value of the data. The purpose of the data includes the function control signal of the object device, the setting of the function parameter or the firmware update, and the function value includes the function control signal value, the function parameter, or the firmware update code.

The data format converter 415 rearranges the classified data in the order of the fields of the message format used by the object apparatus according to the object apparatus data format information 412 and inserts the identifier of the message format between the fields . The data format converter 415 converts the data types and units of each field into types and units used by the embedded processor (e.g., MCU).

Upon receiving the converted data from the data format converter 415, the secure channel processor 416 generates a header according to the object device protocol information 413, reconstructs a message including the generated header and the converted data, Encrypts the data of the reconfigured message using the object appliance authentication information 414, and transmits the encrypted message to the object device.

Virtualized object 410 included in virtualized object resource pool 133 processes a message sent through a secure channel by the object device. The secure channel processor 416 decrypts the encrypted data using the object device authentication information when the message is transmitted from the object device, and separates the header area of the message and the data area of the message according to the object device protocol information 412.

The data format converter 415 extracts the data of the message from the data area of the message separated by the secure channel processor 416 using the order and the identifier of the data field included in the object device data format information 412, To the web interface processing unit 131 and the web server in the format of the language specified in the data structure of the message.
