Abstract

A multifunctional OTP(One-Time Password) token is provided to enable a user to use a public certificate safely by enabling an embedded smart chip to generate an OTP for using the public certificate, and be unnecessary for the user to carry several storage media and cards due to performing a storage, traffic payment, ID card, and credit card function in one OTP token. A USB(Universal Serial Bus) interface(4) for connecting to an external device is installed to one end of a case(1). A USB controller(5), a smart chip(7), and an RFID(Radio Frequency IDentification) chip are embedded in the case. The smart chip stores a memory area by encrypting a public certificate received through the USB controller and generates the public certificate encrypted by using a private key of the public certificate through autonomous operation when the external device requests the public certificate. The RFID chip has a traffic payment, ID card, and credit card function. The RFID chip provides payment information to an MCU(Micro Control Unit)(6) and the MCU displays remainder information in a display unit(2) by calculating the remainder information based on the received payment information when a fare is paid with the RFID chip.

Description

다기능 오티피 토큰{OTP Token}Multifunction OTP Token

본 발명은 다기능 OTP 토큰에 관한 것으로서, 특히 전자금융거래시 인증 보안 매체인 OTP(One Time Password) 번호를 발생시키는 용도로 사용되는 OTP 토큰으로 공인인증서를 저장시킬 수 있음은 물론 내장된 RFID칩을 이용하여 대중교통요금 지불, 출입증, 신용카드기능을 구현할 수 있도록 한 다기능 OTP 토큰에 관한 것이다.The present invention relates to a multifunctional OTP token, and in particular, an electronic certificate can be stored as an OTP token used for generating an OTP (One Time Password) number, which is an authentication security medium in electronic financial transactions, as well as an embedded RFID chip. The present invention relates to a multifunctional OTP token that enables users to implement public transportation fee payment, pass and credit card functions.

일반적으로 OTP 토큰이라 함은 휴대가 가능한 크기의 케이스 내부에 OTP 번호를 발생시키는 OTP발생모듈을 내장시키고, 케이스 표면에는 OTP발생모듈에서 발생된 OTP 번호를 표시하여 사용자가 전자금융거래 중에 이체시 인증매체로서 OTP 번호를 사용할 수 있도록 하는 것을 말한다.In general, the OTP token is embedded with an OTP generation module that generates an OTP number inside the case of a portable size, and the OTP number generated on the OTP generation module is displayed on the case surface to allow the user to authenticate during the electronic financial transaction. The OTP number can be used as a medium.

OTP 토큰을 사용하게 되면 사용자가 전자금융거래를 할 때 이체시 사용되는 인증매체인 OTP 번호가 외부에 노출되지 않게 되므로 보안효과가 뛰어난 장점이 있으며, 이러한 이유로 점차 OTP 토큰의 사용이 대중화되고 있는 추세이다.When OTP token is used, OTP number, which is an authentication medium used when transferring users in an electronic financial transaction, is not exposed to the outside, which has an excellent security effect. For this reason, the use of OTP token is becoming more popular. to be.

그러나, 종래의 OTP 토큰은 OTP 번호를 발생시켜 표시해주는 기능만을 제공하는 것이기 때문에 다양한 기능을 제공하지 못하는 문제점이 발생하고 있었다.However, since the conventional OTP token provides only a function of generating and displaying an OTP number, there is a problem in that it cannot provide various functions.

즉, 전자금융 거래중 인터넷 뱅킹을 이용하기 위해서는 필수적으로 공인인증서가 필요한데, 공인인증서를 컴퓨터의 하드디스크에 저장시켜놓은 상태로 이용하게되면 보안에 취약해져 해킹의 위험이 발생하게되고, 이러한 이유로 점차 이동식 저장매체(예를들면 USB 메모리)에 저장시켜 휴대하는 경우가 증가하고 있으며, 이러한 경우 OTP 토큰과 이동식 저장매체를 별도로 휴대해야만 하는 문제점이 발생하고 있었다.In other words, in order to use Internet banking during electronic banking transactions, an accredited certificate is necessary. If the accredited certificate is stored on the computer's hard disk, it is vulnerable to security and causes a risk of hacking. Increasingly, portable devices are stored in portable storage media (eg, USB memory). In this case, the OTP token and the portable storage media have to be carried separately.

또한, 전철, 버스와 같은 대중교통을 이용할때 RFID칩이 내장된 카드를 이용하고 있으며, RFID칩의 활용은 신용카드로도 사용될 정도로 점차 그 활용범위가 증가하고 있는 상태이고, 상기 RFID칩이 내장된 카드를 사용할 경우 사용자는 OTP 토큰 및 이동식 저장매체와 더불어 RFID칩이 내장된 카드를 별도 휴대해야만 하는 문제점이 발생하고 있었다.In addition, when using public transportation such as trains and buses, a card containing an RFID chip is used, and the utilization range of the RFID chip is gradually increasing to be used as a credit card. In the case of using the old card, a user has to carry a separate card containing an RFID chip together with an OTP token and a mobile storage medium.

따라서, 본 발명은 사용자의 편리성 증대를 위해 OTP 토큰에 공인인증서를 저장할 수 있는 수단을 내장시키면서 RFID칩을 내장시켜 사용자가 여러개의 저장매체를 휴대하지 않아도 되도록 하고자 한다.Accordingly, the present invention is intended to prevent users from carrying multiple storage media by embedding an RFID chip while embedding a means for storing a public certificate in an OTP token to increase user convenience.

상기 USB 콘트롤러를 통해 수신된 공인인증서(공개키+개인키)를 암호화하여 자체 메모리영역에 저장하면서 외부기기로부터 공인인증서 요청시 자체적으로 연산동작하여 공인인증서의 개인키를 이용해 암호화된 인증서를 생성 출력하는 스마트칩을 케이스 내부에 내장한 것을 특징으로 한다. While encrypting the public certificate (public key + private key) received through the USB controller and storing it in its own memory area, it generates an encrypted certificate using the private key of the public certificate by operating on its own when requesting a public certificate from an external device. It is characterized in that the smart chip is built into the case.

본 발명에 의하면, OTP 토큰의 케이스 내부에 공인인증서 저장매체로서 스마트칩을 내장함에 따라 공인인증서 사용시 연산동작을 스마트칩이 차체적으로 수행하므로 공인인증서의 해킹위험이 적어져 공인인증서를 안전하게 사용할 수 있으며, OTP 토큰 하나에 OTP번호 발생기능 이외에도 공인인증서 저장 및 교통비용지불, 출입증, 신용카드 기능을 동시에 구현할 수 있으므로 사용자가 여러개의 저장매체 및 카드를 휴대하지 않아도 되는 효과를 기대할 수 있다.According to the present invention, since the smart chip performs the operation operation when the authorized certificate is used as the smart chip is embedded as a certificate storage medium in the case of the OTP token, the risk of hacking of the certificate can be reduced and the certificate can be safely used. In addition to the OTP number generation function in addition to the OTP number generation function, it is possible to implement the authentication certificate storage and transportation cost payment, pass and credit card functions at the same time, so that the user does not have to carry multiple storage media and cards can be expected.

◈ 공인인증서 저장기능 ◈◈ Certificate storage function ◈

사용자가 공인인증서의 다운로드를 위해 USB 인터페이스(4)를 컴퓨터의 USB 단자에 접속시킨 후 컴퓨터에 저장되어 있거나 아니면 인터넷을 통해 접속되어 있는 금융기관으로 부터 다운로드되는 공인인증서를 USB 인터페이스(4)로 다운로드하 면, USB 콘트롤러(5)는 USB 인터페이스(4)를 통해 다운로드되는 공인인증서(공개키+개인키)를 스마트칩(7)으로 공급한다.The user connects the USB interface (4) to the USB terminal of the computer for downloading the certificate, and downloads the certificate to the USB interface (4), which is stored on the computer or downloaded from a financial institution connected through the Internet. Then, the USB controller (5) supplies the smart chip (7) public certificate (public key + private key) downloaded through the USB interface (4).

상기 스마트칩(7)은 다운로드되는 공인인증서를 자체 구비된 메모리영역에 저장한다.The smart chip 7 stores the downloaded official certificate in its own memory area.

상기 스마트칩(7)은 하나의 IC칩 형태이기 때문에 보안이 뛰어나고, 이로인해 스마트칩(7)에 저장된 공인인증서의 해킹위험이 적은 장점이 있다.Since the smart chip 7 is in the form of a single IC chip, security is excellent, and therefore, there is a low risk of hacking the authorized certificate stored in the smart chip 7.

한편, 사용자가 인터넷뱅킹을 위해 USB 인터페이스(4)를 컴퓨터의 USB단자에 접속시키면, 컴퓨터에서 공인인증서를 USB콘트롤러(5)를 통해 스마트칩(7)에 요구하게되고, 스마트칩(7)은 공인인증서 요구시 자체 메모리영역에 저장되어 있는 공인인증서의 개인키를 이용하여 자체적으로 암호화된 인증서를 생성한 후 USB 콘트롤러(5)를 통해 컴퓨터로 전송하여 인증이 이루어지도록 한다.On the other hand, when the user connects the USB interface (4) to the USB terminal of the computer for Internet banking, the computer requests the smart chip (7) via the USB controller (5), the smart chip (7) When requesting a public certificate, the self-encrypted certificate is generated by using the private key of the public certificate stored in its own memory area, and then transferred to a computer through the USB controller 5 so that authentication is performed.

상기 설명과 같이 본 발명은 공인인증서 저장매체로서 자체 구비된 메모리영역에 공인인증서를 저장하는 스마트칩(7)을 사용하므로 공인인증서의 해킹에 대한 보안 안정성이 매우 뛰어나며, 또한 스마트칩(7)에서 자체적으로 연산동작하여 암호화된 인증서를 생성하여 출력하므로 이 또한 보안 안정성 향상에 기여한다.As described above, the present invention uses a smart chip (7) for storing the certificate in the memory area provided in the self-equipped memory area as the certificate storage medium is very excellent security stability against hacking of the certificate, and also in the smart chip (7) It also contributes to security stability because it generates and prints the encrypted certificate by operating on its own.

기존에는 암호화된 인증서 생성동작을 컴퓨터의 CPU가 실시하게 되므로 이때 해킹의 위험이 발생하게 되나, 본 발명에서는 스마트칩(7) 자체에서 연산이 이루어지므로 외부에서 해킹을 위해 침입할 수 없게되는 것이다.Conventionally, since the CPU of the computer performs the encrypted certificate generation operation, there is a risk of hacking. However, in the present invention, since the operation is performed in the smart chip 7 itself, it cannot be intruded for hacking from the outside.
