At this time, the second device 50 checks the state of the power supply and the screen display unit 58, etc. of the second device (step S24), and confirms the power supply and operation states of the PC (step S25).

Then, the second device 50 receives new data information from the first device 40 (step S26). At this time, the received data information is information about the system security and operation status of the PC.

Then, the second device 50 receives data (command) from the user or transmits the received data to the first device 40 (step S27).

Then, the second device 50 operates after performing a command by data (command) input by the user (steps S28-S29).

If the second device 50 inputs an interrupt command from the user during operation (step S31), the second device 50 selects one of the following three menus, or terminates the program. That is, when an interrupt instruction is input from the user (step S31), an information request menu (step S32) for requesting all the information set by the environment setting mode to the PC and an information selection menu for selecting specific information (step S33). ) And an information deletion menu (step S38) for deleting the received information.

If the user selects the information request menu, the second device 50 transmits it to the first device 40 (step S37), whereby all information set by the environment setting mode is transmitted from the PC. Receive

If the user selects the information selection menu, the second device 50 asks the user of the operation status information request menu (step S34) of the PC, and a security information request menu (step S35) regarding the security status of the PC. ), And selects one of the other menus S36 for selecting other information.

Here, if the user selects the operation status information request menu, the second device 50 transmits it to the first device 40 (step S37), whereby it is set by the configuration mode from the PC. Receive operation status information.

If the user selects the security information request menu, the second device 50 transmits it to the first device 40 (step S37), whereby the security information set by the environment setting mode is transmitted from the PC. Receive

If the user selects the other menu and inputs desired information, the second device 50 transmits the information input by the user to the first device 40 (step S37), whereby the corresponding PC. Receives the information set by the environment setting mode.

Finally, if the user selects the information deletion menu (step S38), the second device 50 provides the user with a list of information regarding the security and operating status of the PC received, The user looks at this list and selects and deletes unnecessary information (step S39).

9 is an explanatory diagram for explaining data encryption and decryption according to the present invention.

In general, in the case of data encryption on the Internet, a data format is encrypted, sent, and decrypted. However, in the present invention, as shown in FIG. 9, in the first device 40 transmitting the data 410 or 450, a user sets and inputs a password with the user-defined encryption key 420, and with the set password. Data 410 or 450 is encrypted and transmitted to the second device 50. The second device 50 reads the data by decrypting (decrypting) the encrypted data 410 or 450. At this time, the user sets and inputs a password to the first device 40 and the second device 50.

Conventionally, only the header portion of a packet and a file is encrypted when encrypting data. However, in the present invention, when transmitting and receiving a small amount of data, the entire header and data are encrypted and transmitted. In the present invention, there is also a data encryption method for fragment encryption of data for each segment.

10 is a flowchart illustrating a data encryption and decryption step according to the present invention.

As shown in FIG. 10, the steps of encrypting and decrypting data are as follows.

First, a user inputs a user-defined encryption key 420 to the first device 40 and the second device 50 (step S71).

Then, when a data transmission or reception command is issued (step S72), the presence or absence of a user-defined encryption key is checked (step S73), and the data to be transmitted and received is encrypted or decrypted using the user-defined encryption key 420 (step S74)

Here, the method of encrypting the data is as follows.

For example, assume that the monitoring information data is composed of (a1, b1, c1), and the user-defined encryption key 420 is composed of (a2, b2, c2).

The encryption key a2 is added to the monitoring information data a1, b1, and c1, respectively, and the encryption key b2 and c2 are repeated in the same manner to generate the following encrypted data.

(a1 + a2, b1 + a2, c1 + a2)

(a1 + b2, b1 + b2, c1 + b2)

(a1 + c2, b1 + c2, c1 + c2)

At this time, when the generated encrypted data is transmitted from the first device 40 to the second device 50, the second device 50 receiving the encrypted data is encrypted using the stored user defined encryption key 420. The decrypted data is decrypted in the reverse order of the encryption steps.

In addition, the network user 503 via the network could also access the open service port 507 and enter the user PC only if the password of the user PC is known.

However, in the present invention, as shown in FIG. 11B, when another console user 511 other than the user accesses the user PC, the access control 510 blocks the access. Even if 511 knows the password of the user PC, access is made impossible.
