Description

금고용 원격조정무선개폐장치{Wireless Remote Control Door Open System For Safe}[0001] The present invention relates to a wireless remote control door opening system,

본 고안은 금고의 외부에 적외선을 수신하는 창을 제외한 자물쇠, 다이알(도1A), 전자키패드(도1B) 등의 일반적인 방법으로 문을 열고 닫는 장치를 부착하지 않음으로, 외부에서 볼 때 어떤 방식으로 문이 열리고 잠그는 지, 또는 어느 위치에 문을 잠그는 빗장이 설치되어 있는지를 알 수 없게 한 금고용 원격조정 무선개폐장치(도2)이다.The present invention does not include a device for opening and closing a door by a general method such as a lock, a dial (FIG. 1A), and an electronic keypad (FIG. 1B) except a window for receiving infrared rays outside the safe, (FIG. 2) which makes it impossible to know whether the door is opened and locked or where the door lock bar is installed.

이러한 종래의 전자식 개폐장치의 경우에는 1) 외부에서 빗장의 위치의 식별이 가능하여 해당 부위를 파괴할 경우, 문을 해체 시킬 수 가 있었고, 2) 소형금고의 경우에는 불편한 자세로 구부리고 앉아 비밀번호의 입력작업이나 반드시 문을 연후에 금고 문 안쪽의 리셋 버튼을 누른 뒤에 비밀번호를 변경해야 하는 번거로움이 있었으며, 3) 동일한 비밀번호를 오랜 기간 사용한 경우 키 패드 표면이 마찰로 마모 반사되어 사용중인 비밀번호가 노출되는 위험이 있었다.In the case of such a conventional electronic opening / closing apparatus, 1) it is possible to identify the position of the bolt from the outside, thereby breaking the door when it is destroyed; 2) in the case of a small safe, 3) If the same password has been used for a long period of time, the surface of the keypad will be abraded with friction, and the password being used will be exposed. There was a danger of becoming.

첫째, 입력된 신호를 송신만 하는 일반적인 가전제품 제어용의 리모트컨트롤러와는 다른 개념이고, 금고의 문과 별도로 분리되어 구성되어 있으며, 입력, 변조, 송신(18) 및 수신(19)의 기능이 갖추어진 양방향성 원격 무선암호입력장치(1)와First, it is a concept different from a remote controller for general household appliance control which transmits only an input signal. It is separated from the door of the safe and has functions of input, modulation, transmission 18 and reception 19 The bidirectional remote wireless password input device 1 and the bi-

둘째, 수신된 신호를 변조시켜 메모리(13)에 저장되어 있는 암호와 일치할 때 원격 무선입력장치에는 이상 없음의 확인신호를, 금고문에 부착되어 있는 개폐회로에는 열림의 명령어를 포함한 전기신호를 보내서 솔레노이드 코일(3)을 작동시켜 금고가 열리게 하는 수신, 변조, 확인, 작동의 기능이 갖추어진 개폐장치(2)와,Second, when the received signal is modulated to match the password stored in the memory 13, an error signal is sent to the remote wireless input device, and an electric signal including a command to open the opening / An opening / closing device 2 having functions of receiving, modulating, confirming and operating the solenoid coil 3 to operate so as to open the safe,

셋째, 원격무선입력장치(1)와 원격무선개폐장치(2)가 무선으로 데이터를 주고받을 때 발생할 수 있는 암호노출의 위험을 완벽하게 제거하기 위하여, 고정암호(15)와 임의인증암호(16) 및 반송파(17)를 곱하여 송수신하게 함으로써 신호를 노이즈화하고 교신할 때마다 임의인증암호가 바뀌게 하는 CPU용프로그램의 제작(도5, 도6)에 그 기술적 과제를 둔다.Third, in order to completely eliminate the risk of password exposure that may occur when the remote wireless input device 1 and the remote wireless switching device 2 exchange data wirelessly, the fixed password 15 and the random authentication password 16 (Fig. 5 and Fig. 6) for changing the arbitrary authentication code every time the signal is made to be noise and made to communicate by multiplying it by the carrier wave 17 and the carrier wave 17 (Figs. 5 and 6).

본 고안은 1) 비밀번호를 입력시키고, 입력된 비밀번호를 암호화(Encoding)하여 송신부(18)에 발신하게 되고 수신부(19)에서 비밀번호, 고정암호(15), 임의인증암호(16)의 일치 여부를 확인하여 반송하는 신호(도6)를 수신하는 양방향성 즉 발신과 수신이 가능한 원격무선암호입력장치(1)와 2)원격무선암호입력장치(1)에 입력되어 암호화, 발신된 신호를 수신하여 디지털신호로 변환(Decoding)시키고, 원격 무선 암호입력장치에 확인하여 무선개폐장치(2)의 회로에 신호를 발신하고, 또, 비밀번호 변경시에는 CPU(12)에 부착된 플레쉬메모리(13)에 저장시키는 수신 및 변환부, 3) 상기 수신 및 변환부에서 전달된 개폐신호를 접수하여 솔레노이드 코일(3)을 작동시키는 작동부로 구성된다.In the present invention, 1) a password is entered, and the inputted password is encrypted and transmitted to the transmitter 18, and whether or not the password, the fixed password 15 and the random authentication password 16 are matched in the receiver 19 A remote wireless encryption input device 1 capable of receiving and transmitting signals (Fig. 6) for confirming and transmitting the received signals, 2) a remote wireless encryption input device 1 for receiving the encrypted and originated signals, Signal to the circuit of the wireless switchgear 2 and confirms the password in the flash memory 13 attached to the CPU 12 when the password is changed And 3) an operation unit for operating the solenoid coil 3 by receiving the open / close signal transmitted from the receiving and converting unit.

본 고안은 2단계의 암호체계를 가지며, 3개의 암호를 가지고 작동한다. 이중 임의인증암호(16)는 무선의 단점인 감청으로 인한 암호 노출을 방지하기 위하여 원격무선암호입력장치(1)와 원격무선개폐장치(2)가 금고를 열 때마다 변경하면서 통신하며 변환 갱신된다.This scheme has two levels of cryptography and operates with three ciphers. The dual random authentication code 16 communicates with the remote wireless encryption / decryption device 1 and the remote wireless switching device 2 every time the safe is opened to prevent the password from being exposed due to interception, which is a disadvantage of wireless communication, .

1. 비밀번호 : 사용자가 원격무선암호입력장치(1)에 입력하는 사용자 암호를 말하며, 사용자가 허가된 사용자인지를 확인할 수 있다. 특정횟수이상 틀린 암호를 연속 입력할 때는 원격무선암호입력장치가 일정시간 후 동작하게 하여 외부인의 침범을 막게 한다.1. Password: a user password input by the user to the remote wireless password input device 1, and can confirm whether the user is an authorized user. When the wrong password is inputted continuously more than a certain number of times, the remote wireless password input device is operated after a predetermined time, thereby preventing the invasion of the outsider.

2. 고정암호(15) : 제작당시 원격무선암호입력장치(1)와 원격무선개폐장치(2)에 입력하는 고정된 암호이다. 저장은 Flash Memory(10,13)에 저장하며, 누출 및 수정될 수 없도록 Flash Memory를 Locking해놓는다.2. Fixed code (15): It is a fixed code to be inputted into the remote wireless password input device (1) and the remote wireless switchgear (2) at the time of production. The storage is stored in the Flash memory (10, 13), and the flash memory is locked so that it can not be leaked or corrected.

3. 임의인증암호(16) : 원격무선암호입력장치(1)와 원격무선개폐장치(2)가 서로를 확인할 수 있도록 사용된 암호이다. 금고가 열릴 때마다 금고문에 장치되 원격무선개폐장치(2)의 회로에 내장되어 있는 CPU(12)내의 프로그램이 매번 통신 후 새롭게 변경된 임의인증암호(16)를 만들어 원격무선암호입력장치(1)에 알려주고, 원격무선암호입력장치(1)는 다음통신에 사용할 수 있도록 이 암호를 Flash Memory(10)에 저장한다. 이렇게 변경된 임의인증암호(16)를 사용해서 통신하므로, 외부 계측기 또는 감청기로 무선신호를 감청해도 매번 다르게 나타나고, 동일한 무선신호가 감청 녹음되어 수신부(19)에 접수되는 경우에도 다른 신호로 변환되었기 때문에 반응하지 않는다. 다시 말해, 무선신호의 감청재생은 가능하여도, 임의인증암호(16)는 노출되지 않는다.3. Random authentication password (16): The password used for the remote wireless password input device (1) and the remote wireless switching device (2) to identify each other. Each time the safe is opened, the program in the CPU 12 incorporated in the circuit of the remote radio switchgear 2, which is installed in the gold tin door, generates a random authentication code 16 newly changed after communication each time, And the remote wireless password input device 1 stores this password in the flash memory 10 so that it can be used for the next communication. Since the communication is performed using the arbitrary authentication password 16 thus modified, even if the radio signal is audited by the external measuring instrument or the audition device, the same radio signal is different every time, and even when the same radio signal is received by the receiving section 19, It does not react. In other words, arbitrary authentication code 16 is not exposed even if the wireless signal can be audibly reproduced.

이 기술의 가장 난해한 것은 임의인증암호를 만들어내는 생성기이다. 이 생성기의 조건은 비반복 및 불규칙적이어야 한다. 보통 이런 식의 생성기는The most challenging aspect of this technique is the generator that generates arbitrary authentication ciphers. The conditions of this generator should be non-iterative and irregular. Usually this type of generator

y=f(x), x=1, 2, 3, ….. 100y = f (x), x = 1, 2, 3, ... .. 100

으로 정의하여 어떤 수식에 규칙적인 수를 대입한 것으로 계산되지만, 본 고안에서는 혼돈(Chaos)이론에 적용되는 플렉털함수를 사용했다., Which is calculated by assigning a regular number to a certain expression. In this case, however, we use a fractal function applied to Chaos theory.

이 함수는This function

y1=f1(x)·f2(x),y 1 = f 1 (x) · f 2 (x),

y2=f1(y1)·f2(y1),y 2 = f 1 (y 1 ) · f 2 (y 1 ),

y3=f1(y2)·f2(y2),y 3 = f 1 (y 2 ) · f 2 (y 2 ),

y4=f1(y3)·f2(y3),y 4 = f 1 (y 3 ) · f 2 (y 3 ),

..

..

으로 표현된다. 이런 함수는 발산 또는 수렴되기 쉬우나 f(x)와 x를 Computer Simulation을 실행해서 선택하면 수렴대에서 무한한 임의 변수를 만들어 낼 수 있다. 이렇게 해서 만들어진 임의인증암호(16)는 매우 불규칙적이어서 임의인증암호로서의 효용성이 높다.. These functions are easy to diverge or converge, but if you select f (x) and x by running Computer Simulation, you can create an infinite random variable in the convergence. The arbitrary authentication password 16 thus generated is very irregular and thus has high utility as an arbitrary authentication password.

4. 금고를 여는 방법 및 순서는 [도 7], 금고의 비밀번호를 변경하는 방법 및 순서는 [도 8] 에 의한다.4. The method and order of opening the safe are as shown in Fig. 7, and the method and order of changing the password of the safe are as shown in Fig.

이상에서와 같이 본 고안에 의하면, 금고에 원격무선개폐장치(2)를 내장하고, 원격무선암호입력장치(1)를 이용하여 금고문을 개폐함으로써, 1) 전면에 어떠한 장치도 장착되지 않기 때문에 금고인지를 인식할 확률이 적고, 2) 빗장의 위치식별이 불가능하여 금고문의 강제적인 해체 위험이 없고, 3) 매번 통신할 때마다 새로운 임의인증암호(16)를 사용하기 때문에 암호 노출이 불가능하고, 4) 암호의 변경이 수윌하다.As described above, according to the present invention, since the remote control device 2 is installed in the safe, and the remote control device 1 is used to open and close the door, 1) (2) there is no danger of forcible disassembly of the safe because the position of the bolt can not be identified; (3) a new random authentication code (16) is used every time communication is performed; , 4) the password must be changed.
