System server 10 including a server, network communication network 20, home PC 30, office PC 32, first device 40,

Pocket PC 60 with second device 50, second device 62 of card or cradle type, mobile trough with second chip device 72

It is configured to include a new terminal 70

The first device 40 is an external interface of the home PC 30 or the office PC 32 connected to the network communication network 20.

Is connected to and attached to an ear (not shown). The first device 40 will be described in detail with reference to FIGS.

The home PC 30 or the image by a setting program of a daemon (RAM resident program) stored in a memory (not shown).

After setting the user's environment for the office PC 32, the home PC 30 or the office PC 32

The second device may monitor information (processing system security and operating state of the PC, etc.) of processing necessary data by monitoring at regular intervals.

The first device 40 is a daemon stored in its memory when connected to the home PC 30 or the office PC 32.

and a Plug & Play (PnP) function for automatically operating mon).

As shown in FIG. 1, when the device 40 is installed at an external interface of a PC or a server,

The daemon stored in Mori can be stored and operated in the memory of the PC or server.

The method of transmitting data from the first device 40 to the second device 50 uses wireless communication.

Includes radio frequency (RF), wireless LAN (LAN), wireless mobile network

In addition, the user's environment for the home PC 30 or the office PC 32 may be secured according to the user's demand level.

Network access, network, file and directory hacking, etc.), user macros, etc.

As shown in FIG. 5, the second device 50 is configured to be easily carried by a user.

Information about the system security and operation status of the PC received from the device 40 is displayed on the display window.

7 is a flowchart illustrating an operation of a PC to which a first device is connected according to the present invention.

First, when the first device 40 is connected to the interface module of the home PC 30 or the office PC 32, the first device

The configuration program of the daemon stored in the device 40 operates to set environment setting modes such as system security use level and user macro.

(Step S11) Then, monitoring is performed at regular intervals (Step S12), and then the operation in each set environment setting mode is searched and entered in the environment setting mode.

Search for what action is taking place (steps S13-S14). For example, in the case of system security,

If someone else uses your PC, try again

Then, if any operation occurs in step 14 (S14), based on the hooking library to check the system security and operation status

Check (step S15) and standardize the information (step S16).

Then, the parsed information is encrypted (step S17) and transmitted to the second device 50 through the first device 40 (step S18).

8 is a flowchart showing the overall operation of the second device 50 according to the present invention.

First, when power is input to the second device 50 (step S21), a program stored in the memory 56 of the second device 50 is loaded.

(Step S22) is a standby state which is a preparation period for exchanging data between the second device 50 and the first device 40 (step

In this case, the second device 50 checks the power supply of the second device, the state of the screen display unit 58, and the like (step S24).

), Check the power supply and operation status of the PC (step S25).

Then, the second device 50 receives new data information from the first device 40 (step S26).

Data information is information about the system security and operation status of the PC.

Next, the second device 50 receives data (command) from a user or receives the received data from the first device 40.

(Step S27)

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

If the second device 50 receives an interrupt command from the user during operation (step S31), the following three menus are used.

Select one of them, otherwise exit the program.

Step S31), an information request menu (step S32) for requesting all information set by the environment setting mode to the PC,

One of an information selection menu (step S33) for selecting print information and an information deletion menu (step S38) for deleting received information.

Choose one

If the user selects the information request menu, the second device 50 transmits it to the first device 40 (step S3).

7) thereby receiving all information set by the configuration mode from the PC.

If the user selects the information selection menu, the second device 50 determines the operation state of the PC to the user.

A device for selecting a request menu (step S34), a security information request menu (step S35) regarding the security status of the PC, and other information.

Select one of the other menus (S36)

Here, if the user selects the operation state information request menu, the second device 50 determines the first device 4.

0) (step S37), thereby receiving the operation status information set by the environment setting mode from the PC.

If the user selects the security information request menu, the second device 50 transmits it to the first device 40.

S37), thereby receiving security information set in the environment setting mode from the PC.

If the user selects the other menu and inputs desired information, the second device 50 inputs the user input.

Information is transmitted to the first device 40 (step S37), whereby the information set in the configuration mode is received from the PC.

God receives

Finally, if the user selects the information deletion menu (step S38), the second device 50 sends the user

Provides a list of information regarding the security and operational status of the PC received and the user needs to view this list

Select and delete the missing 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, the data format is encrypted, sent, and decrypted.

However, in the present invention, as shown in FIG. 9, the first device 40 transmitting data 410 or 450 is used.

The user sets and enters a password with a custom encryption key (420) and encrypts the data (410 or 450) with this set password.

The second device 50 reads the data by decrypting (decrypting) the encrypted data 410 or 450. In this case, the user reads the data. ) And set a password on the second device 50

do

Conventionally, when encrypting data, only the header of the packet and the file is encrypted, but in the present invention, a small amount of data

In the present invention, the header and the data are encrypted and transmitted.

There is also a data encryption method for fragment encryption for each segment.

10 is a flowchart showing 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 command to send or receive data is issued (step S72), it is checked whether or not a user-defined encryption key is present (step S73), and then the transmission

The data to be 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, the monitoring information data is composed of (a1, b1, c1), and the user-defined encryption key 420 is composed of (a2, b2, c2)

Assume

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

Generates encrypted data such as

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

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

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

At this time, if the generated encrypted data is transmitted from the first device 40 to the second device 50, the second device (

50) decrypts the encrypted data using the stored user defined encryption key 420 in the reverse order of the encryption steps.

Decrypt
