As a method of connecting a private smart device to an internal network such as a workplace, an internal network security officer acquires identification information (SSID, MAC address, etc.) of a terminal owned by an individual employee, registers the terminal in the network authentication server, The employee searches for the SSID of the internal network at the terminal and accesses the internal network through the input of an account and a password.

However, in the conventional connection method described above, it is extremely inconvenient for individual employees to search for and access the network, and the security officer must update the information about the corresponding items when the employee enters or exits. Therefore, There is a problem that both the security officer and the individual staff feel hassle in connection.

It is an object of the present invention to provide a technique for implementing an easy connection of a user terminal to an internal network using two different QR codes.

The above object is achieved according to the present invention by a method comprising: a first step of generating and distributing a first QR code at a management server; A second step in which the first QR code distributed in the first step is recognized by the user terminal; A third step of generating and distributing a second QR code for the group network in a group server linked to the management server; A fourth step in which the second QR code distributed in the third step is recognized by the user terminal; A fifth step of requesting a user terminal to access a network of the corresponding group using the information included in the second QR code; And a sixth step of authenticating whether the network server is connected to the network according to the request from the authentication server in the fifth step.

Here, the first QR code includes link information of a market for storing the network connection management application.

In addition, the second QR code includes information for activating the network connection management application and information (SSID, encryption information) about the network connection profile of the corresponding group.

Here, after the second step, the network access management application may be downloaded and installed in the user terminal.

The method may further include a fourth step of, after the fourth step, analyzing a network connection profile included in the second QR code by driving the network access management application at a user terminal.

In the fifth step, the SSID and the encryption information of the group network analyzed in the step 4-1, and the identification information of the user terminal are transmitted to an access point (AP) of the corresponding group network, This is the requesting step.

In the sixth step, the AP requests authentication of the user terminal to the authentication server of the corresponding group network to determine whether to connect.

According to the present invention, the following effects can be obtained.

First, a network connection can be automatized using a first QR code including information on a connection management application, a second QR code including information for activating the connection management application, and network profile information of the corresponding group.

Second, since the connection management application does not include the network profile information of the group, the connection management application can be branded as a product, and can be universally applied to various fields.

Third, because the connection management application is installed in each user terminal, the security officer does not need to change or update the internal network system when building the BYOD environment, so that the internal network security problem is solved and the internal network connection of the user terminal can be easily implemented have.
