It is to be understood, however, that the invention is not to be limited to the specific embodiments, but is to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention, And the scope of the present invention is not limited to the following examples.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings, wherein like or corresponding elements are denoted by the same reference numerals, and redundant explanations thereof will be omitted.

1 is a block diagram illustrating a hacking freeboard communication system using a guardian module according to an embodiment of the present invention.

Referring to FIG. 1, a hacking freeron communication system 10 using a guardian module according to an embodiment of the present invention may include a public drones 100 and a drones controller 300.

The public drones 100 are provided with a first guardian module 110 using an ARIA encryption decryption algorithm so that the first guardian module 110 encrypts and transmits images and data, Receives the operation signal of the dragon terrestrial control device 300 encrypted and decrypts it, and operates according to the operation signal.

The air drone 100 includes a navigation sensor unit 120 for acquiring data necessary for flight, a camera 130 for acquiring an external image, a GPS 160 for acquiring data on the flight position, And outputs the control signal corresponding to the operation signal received and decoded by the first guardian module 110 to the image obtained through the camera 130 or acquired through the GPS 160 A first guardian module 110 which is controlled by a control signal from the flight control section 170 to control the first guardian module 110 to transmit data encrypted and transmitted by the first guardian module 110, A plurality of driving units 210 for generating driving force required for switching directions, and a power supply unit 190 for supplying power necessary for operation. Here, the navigation sensor unit 120 may include a single sensor or a plurality of sensors for detecting speed, attitude, inclination, altitude, obstacles on a flight path, and the like necessary for controlling the flight. The power supply unit 190 may be a rechargeable rechargeable battery or may be a conventional battery. The driving unit 210 may be a motor in which a propeller is fixed to a rotary shaft. The air drone 100 further includes a light source 140 for irradiating light to the photographing area of the camera 130, a microphone 150 for acquiring audio from the outside, and various data, setting values, data A storage unit 180 for storing programs and the like may be provided.

Referring to FIG. 2, the first guardian module 110 uses an RJ-45 Internet port and a general serial port (RS-232) channel in the same manner as the second guardian module 310 to be described later. And is divided into a physical layer and a data link layer. The data link layer is divided into a media access (MAC) sublayer and an adaptation sublayer. The medium access layer uses a hybrid multiple access (HMA) scheme, which utilizes the characteristics of the physical layer, binary CDMA, to access the medium through a combination of codes and time slots. The advantage of binary CDMA is that it can transmit the modulated signals of various levels generated in the existing multi-code CDMA system to the TDMA signal waveform in an outward form, thereby enabling high-speed transmission with low noise CDMA characteristics and low power consumption TDMA (Time Division Multiple Access). The adaptation sublayer serves to make the lower protocol stack compatible with the protocol stack of the other wireless standards.

The guardian technology by the first guardian module 110 and the second guardian module 310 is a domestic wireless technology standard that combines binary CDMA technology and ARIA, a NIS security algorithm. Conventional wireless communication technologies have a problem in that it is difficult to utilize variously in a home network due to a heavy power consumption, and transmission / reception is not smooth due to radio wave interference when transmitting large amounts of data. In contrast, the Guardian technology combines the advantages of CDMA and TDMA technology, and is characterized by strong noise immunity as compared to wireless LAN and Bluetooth, and is capable of transmitting data at very high speeds while consuming low power. Compared with other short-range wireless communications, the ability to transmit and receive long distances is far superior. As a result, Guardian technology can transmit and receive data (video and voice) up to 500 meters without a base station when LOS is guaranteed, and can freely transmit and receive video and audio even when moving (60 km / h) . Here, wireless transmission and reception of high-quality images is much freer, and it can be used together with existing wireless communication technology without signal interference, and provides quality of service (QoS) and data encryption function of multimedia service. In particular, independent ad-hoc networks are created between terminals without an access point (AP), and 40 simultaneous use of piconet (piconet: network where two or more devices share the same channel) This enables direct transmission and reception of multimedia data between individuals, individuals, individuals and a plurality of persons.

Also, Guardian technology uses 128bit AES and ARIA encryption decryption algorithm for network security. The encryption algorithm is implemented in hardware in the Soc, so there is little delay in data packet processing due to encryption / decryption. Encryption generally consists of the original data, the key that encrypted it, the encrypted data, and the key to restore the encrypted data back to the original data. The symmetric encryption method and the asymmetric encryption method can be divided according to the encryption key management method. The symmetric cryptosystem is a well known method of encrypting and decrypting the same key and sharing the same key as the other. The asymmetric encryption method uses a public key that is known by anyone who encrypts it, and a secret key when decrypting it. The encryption key, the decryption key, and the key are different from each other. In the transmission network, symmetric keys are used, and the master and slave share the same key to maintain network security. Generally, the format of the unencrypted guardian frame is composed of MAC Header + Payload + FCS.

Referring to FIG. 1, a drones control device 300 is provided with a second guardian module 310 using an ARIA encryption decryption algorithm, so that a second guardian module 310 is provided from the public drones 100 Decrypts the encrypted image or data by application of the wirelessly received ARI, encrypts the operation signal for controlling the operation of the public drones 100, and transmits the encrypted operation signal to the public drones 100. [

The second guardian module 310 encrypts the operation signal input by the operation unit 320 with the application of the aria to the airborne drones 310, The ground control unit 330 controls the second guardian module 310 to control the video and data received from the public drunken 100 to be decoded by the second guardian module 310, The display unit 340 may be configured to display the decoded image or data and the memory unit 350 may store the image or data decoded by the second guardian module 310. In addition, A battery that supplies power, and the like. The operation unit 320 may be a variety of input devices including a handle, a key, a lever, a keyboard, and the like.

According to the hacking freeron communication system using the guardian module according to the present invention, the first and second guardian modules 110 and 310 may be equipped with a powerful ARM9 CPU, All of the control software of the flight control unit 170 of the first and second guardian modules 110 and 310 may be transferred to the first and second guardian modules 110 and 310 to reduce the weight of the public drill 100 and the number of modules.

In addition, the first guardian module 110 may add the function of transmitting data transmitted from the camera 130 because the first guardian module 110 can record the contents photographed by the camera 130 using the video channel. The air drone 100 may be configured to transmit the data of the camera 130 using the video transmission capability of the guardian in real time including the first guardian module 110 of the air drone 100 and the flight control unit 170, It can integrate the entire control module and reduce the weight.
