Abstract

PURPOSE: A wired/wireless telephone security apparatus using a cryptographic key is to provide a small-sized portable wiretap prevention apparatus that converts a user's voice dialogic contents into contents a wiretapper cannot understand in real time using a cryptographic key appointed by a user and that makes the dialogue partner recognize the call contents without difficulty. CONSTITUTION: A voice signal inputted from a microphone(5) of a hands free kit(3) is inputted to a voice conversion/restoration unit(2). The voice conversion/restoration unit(2) encodes and converts the voice signal in real time using a cryptographic key previously set by a user and sends the signal to a telephone connection unit(1). The converted voice signal is transferred to the other side's telephone through a generic wired or wireless phone(6). The converted and transferred signal is inputted to the voice conversion/restoration unit(2) through the telephone connection unit(1) via the generic phone(6). As the signal inputted to the voice conversion/restoration unit(2) is restored with the application of the preset cryptographic key, the user's voice is outputted from the other side's earphone(4) through the hands free kit(3) as the original voice.

암호키를 이용한 유무선 전화 보안 장치{ Hand-held security equipment for telephone using secret key }Hand-held security equipment for telephone using secret key}

본 발명은 휴대 가능한 전화 보안 시스템으로 급증하는 개인 사생활 침해의 한 형태인 전화 도청행위에 대한 근본적인 대처 방안으로 송출되는 음성데이타를 암호키를 적용한 음성변환/환원장치(2)를 통해 실시간 변환하여 도청자가 송수화 내용을 도청하더라도 도청내용을 알아들을 수 없는 내용으로 바꾸어 악용할 수 없도록 하고 정상적인 통화 상대방인 경우 동일한 음성변환/환원장치(2)를 이용하여 미리 약속된 암호키로 암호를 풀어 원래의 음성을 분리해내는 장치 및 기술에 관한 것이다.The present invention provides real-time conversion of eavesdropping voice data through a voice conversion / reduction device (2) using an encryption key. Even if the user taps the contents of the telephone, the contents of the eavesdropping can be changed into unreadable contents, so that they cannot be misused. The present invention relates to an apparatus and a technique for separating.

현재의 전화 보안은 군부대, 정부 보안부서 전화등에서 활용하고 있는 비화기의 경우로 일부 특정 전화에 비화기를 달아 음성통화 내용에 잡음을 넣어 감청 또는 도청자가 잘 알아들을 수 없는 상태로 송수신을 하는 방법이 활용되고 있을 뿐이다. 이외의 유선 전화인 경우 제삼자의 도청이 있을 경우 도청방지 전문가에 의뢰하여 도청에 의한 전류의 변화를 감지해 본인이 도청되고 있는지의 여부 및 도청장치를 찾아내는 형태로 일반 개인인 경우 본인이 도청되고 있는지 여부도 전혀 알지 못하는 사이에 개인의 사생활이 100% 노출될 수 있는 상태에 있으며, 무선전화의 경우는 본인이 도청되고 있다는 사실 여부를 아는 것 조차도 방법이 없어 일반 전화통신인 경우 유무선을 포함하여 음성보안은 현재 전혀 이루어지지 않고 있다.The current telephone security is used for military telephones and government security telephones. In some cases, a specific telephone is used with a telephone to add a noise to the contents of a voice call so that an eavesdropper or an eavesdropper cannot be heard. It is just becoming. In case of other wired telephones, if there is a third party's eavesdropping, ask the eavesdropping expert to detect the change in current caused by the eavesdropping and to find out if the eavesdropping device is being used. Without knowing whether or not the individual's privacy can be exposed 100%, and in the case of wireless phones there is no way to know whether or not you are eavesdropping. There is no security at all.

따라서 본 발명은 이러한 종래 기술의 단점을 보완하고 개선하여 안출한 것으로서, 본 발명의 제1목적은 개인이 지정할 수 있는 암호키를 이용하여 본인의 음성대화 내용을 도청자가 알아들을 수 없는 내용으로 실시간 변환하여 송출하며, 대화 상대자는 어려움없이 통화 내용을 알아 들을 수 있는 도청방지 기술을 개발하여 휴대형 소형 도청방지장치를 제공하는데 있다.Therefore, the present invention has been made to solve and improve the disadvantages of the prior art, the first object of the present invention by using a cryptographic key that can be specified by the person in real time conversion of the voice conversation content to the contents that the eavesdropper can not understand It is to provide a portable small eavesdropping device by developing the eavesdropping technology that the conversation partner can hear the contents of the call without difficulty.

본 발명의 제2목적은 상기 도청방지 기술을 적용하여 유선전화 및 휴대전화내에 도청방지회로를 장착하여 별도의 도청방지 장치를 이용하지 않고도 도청을 원천적으로 봉쇄할 수 있는 회로를 삽입한 전화기를 제공하는데 있다.The second object of the present invention is to provide a telephone with a circuit which can block eavesdropping without using a separate tapping device by installing a tapping prevention circuit in a wired telephone and a mobile phone by applying the tapping prevention technique. It is.

..

상기의 목적을 달성하기 위하여 본 발명은 핸즈프리 키트 부분(3)의 마이크(5)로 부터 입력된 음성신호를 음성변환/환원장치(2)로 입력하게 되고 이 음성변환/환원장치(2)는 도청방지를 원하는 사용자가 미리 설정한 암호키를 이용하여 실시간 음성신호를 암호화 변환하여 전화기 연결부(1)로 보냄으로서 변환된 음성신호는 일반 유무선 전화(6,7)를 지나 중계기, 기지국, 전화국등을 거쳐 일반 대화하는 방식 그대로 상대방 전화에 도달하게 된다. 이렇게 도달된 변환된 신호는 전화기(6,7)를 지나 전화기 연결부(1)를 거쳐 음성변환/환원장치(2)에 입력되게 된다. 음성변환/환원장치(2)에 입력된 변환 신호는 미리 약속된 암호키를 적용하여 원래의 음성으로 환원되며 핸즈프리 키트(3)를 지나 송화자의 음성이 수화자의 이어폰(4)에서 원래의 음성으로 흘러나오게 된다. 음성변환/환원장치(2)는 양단에서 입력되는 신호를 각각 음성의 암호화 변환작업과 암호 변환된 신호의 환원작업의 두가지 기능을 동시에 하게 된다.In order to achieve the above object, the present invention inputs the voice signal input from the microphone 5 of the hands-free kit part 3 to the voice conversion / reduction device 2, and the voice conversion / reduction device 2 is A user who wants to prevent eavesdropping encrypts and converts a real-time voice signal using the encryption key set in advance, and sends the converted voice signal to the telephone connection unit 1. You will reach the other party's phone as you normally would. The converted signal thus reached is input to the voice conversion / reduction device 2 via the telephones 6 and 7 via the telephone connection unit 1. The converted signal inputted to the voice conversion / reduction device 2 is reduced to the original voice by applying a predetermined encryption key, and passes through the hands-free kit 3 to the caller's voice from the receiver's earphone 4 to the original voice. It flows out. The voice conversion / reduction device 2 simultaneously performs two functions, namely, an encryption conversion operation of a voice and a reduction operation of an encryption conversion signal, respectively, for a signal input from both ends.

위의 통화 내용이 전달되는 전화통신망으로는 유선 전화통신망(PSTN)과 무선전화 통신망은 물론 인터넷, 위성 통신망등 음성신호에 영향을 주지 않는 어떠한 통신망에서의 사용도 가능하게 된다.As the telephone communication network to which the above contents are transmitted, it is possible to use in any communication network that does not affect voice signals such as the wired telephone communication network (PSTN) and the wireless telephone communication network as well as the Internet and satellite communication networks.

위의 음성변환/환원장치(2)에서 암호화 변환된 신호의 음성 환원은 특정 암호키 또는 마스터키를 가지고 다른 음성변환/환원장치(2)에서 할 수 있으며 일반인에게 마스터키의 공개는 금지된다. 마스터키는 특정 목적을 위해 적용되며 관련 부처의 요청에 따라 제공하게 된다.The voice reduction of the signal encrypted by the voice conversion / reduction device 2 above can be performed in another voice conversion / reduction device 2 with a specific encryption key or master key and the disclosure of the master key to the public is prohibited. The master key is applied for a specific purpose and will be provided at the request of the relevant ministry.

본 발명은 유무선 전화의 부당한 도청행위로 발생할 수 있는 모든 인권 침해행위를 무력화시키는 기술로 21세기 통신시대에 개인의 통신 사생활 보호 및 일반기업, 정부의 유무선 통신정보, 비밀 송수신 내용의 보호에 안전한 방안을 제시할 수 있다.The present invention is a technology that neutralizes all human rights violations that can occur due to illegal eavesdropping of wired and wireless telephones. Can be presented.
