Description
본 발명의 목적은 인터넷상에서 누구나 쉽게 보안메일을 사용할 수 있도록 하는 것이다.An object of the present invention is to enable anyone to easily use the secure mail on the Internet.
일반 사용자들은 쉽게 메일서비스를 사용하기를 원하며 최근 정보보호의 필요성이 대두되면서 메일 정보의 보안 또한 중요한 요소로 부각되었다.General users want to use mail service easily, and security of mail information has also emerged as an important factor due to the recent need for information protection.
메일을 교환하기 위해서는 메일 소프트웨어가 필요하며 개인 컴퓨터에 소프트웨어를 설치해야 한다. 그러나 설치에 어려움을 느끼는 사람들이 많으며 메일서버와 계정이 필요하기 때문에 누구나 인터넷에 연결된 컴퓨터를 가지고 있다면 인터넷을 통해 편리하게 사용할 수 있는 인터넷메일서비스가 많은 인기를 얻고 있다.To exchange mail, you need mail software, and you need to install the software on your personal computer. However, there are many people who have difficulty in installation and need a mail server and account, so if anyone has a computer connected to the Internet, the Internet mail service, which can be conveniently used through the Internet, is gaining popularity.
본 발명은 인터넷메일서비스에 보안기능을 추가하여 쉽게 보안메일을 교환할 수 있도록 해주며, 디렉토리시스템을 연동하여 보안메일시스템 관리체계를 갖추고 특별한 지식을 가지고 있지 않더라도 단지 적법한 회원 가입절차를 통과하기만 하면 보안메일서비스를 이용할 수 있도록 해준다.The present invention adds a security function to the Internet mail service so that it can be easily exchanged with a secure mail, and has a secure mail system management system in conjunction with a directory system. This allows you to use a secure mail service.
보안메일기술은 메일교환기술에 정보보호기술이 접목된 기술이다. 본 발명에 적용된 정보보호기술은 암호화기술이며 특정 정보에 암호화를 하여 아무나 그 내용을 알 수 없도록 하는 것이다.Secure mail technology is a technology that combines information protection technology with mail exchange technology. The information protection technology applied to the present invention is an encryption technology and encrypts specific information so that no one knows its contents.
기존의 보안메일기술은 PEM, S/MIME, PGP 등이 존재하며, 최종 사용자간의 정보보호서비스를 제공해준다. 이러한 기술들은 암호화를 기반으로 운영된다.Existing secure mail technologies include PEM, S / MIME, and PGP, and provide information protection service between end users. These technologies operate based on encryption.
그러나 각기 형태와 체계가 달라 호환되지 않으며, 실제 운영되고 있지만 통신 기반의 구축 미비로 일반 사용자가 쉽게 접근하기 힘들기 때문에 보안 지식을 보유하고 있는 일부 사용자만이 이용하고 있을 뿐이다. 이러한 문제는 자신이 사용하고 있는 컴퓨터에 보안메일 소프트웨어를 설치해야 하며 다양한 보안 옵션을 설정해야 하기 때문에 어려움이 많아서 발생하는 문제이다.However, they are incompatible with each other in form and system, and they are actually operated, but they are only used by some users with security knowledge because they are not easily accessible to general users due to lack of communication infrastructure. This problem is caused by a lot of difficulties because the security mail software must be installed on the computer you are using and various security options must be set.
CGI(8)는 Common Gateway Interface의 약자로 정적인 HTML 만으로 제공되던웹서비스에서 동적으로 원하는 동작을 서버측에서 수행하여 그 결과를 웹브라우저에 전달해주는 기술이며, Servlet은 JAVA진영의 CGI와 비슷한 기술이다.CGI (8) is an abbreviation of Common Gateway Interface. It is a technology that performs the desired operation on the server side and delivers the result to web browser dynamically in web service provided by static HTML only.Servlet is similar to CGI of JAVA. to be.
본 발명은 인터넷의 웹상에서 보안메일서비스를 제공하고자 하는 것이다. 그러기 위해서는 우선 웹브라우저와 웹서버간에 정보보호가 이루어져야 하며 웹서버에서 동작하는 CGI 및 Servlet 과 메일서버간에 정보보호가 이루어져야 한다.The present invention is to provide a secure mail service on the web of the Internet. To do this, first, information protection must be established between the web browser and the web server, and information protection must be made between the CGI, servlet and mail server running on the web server.
또한 암호는 메일을 발신하는 송신자와 수신하는 수신자사이에서 공유되거나 또는 인지 되어있는 것으로 메일 서비스를 제공하는 업체에서는 책임을 지지 않는다.In addition, passwords are shared or recognized between the sender and recipient of the mail, and are not responsible for the service provider.
이러한 것들은 통합적으로 제공함으로써 일반 사용자가 쉽게 회원가입을 하고 보안메일을 사용할 수 있도록 한다.These are integrated so that general users can easily register and use secure mail.

본 발명의 인터넷메일시스템에서 암호화기술을 이용한 보안메일시스템은 4 가지의 구성요소로 구축된다. 각 6 가지 구성요소는 보안메일시스템(1), 메일서버(2), DBMS(3), 웹브라우저(4) 이다.In the Internet mail system of the present invention, a secure mail system using encryption technology is constructed of four components. Each of the six components is a secure mail system (1), a mail server (2), a DBMS (3), and a web browser (4).
우선, 보안메일시스템(1)은 웹서버(7)를 이용하여 CGI(6) 또는 Servlet(6) 프로그램으로 구축된 메일시스템이다.First, the secure mail system 1 is a mail system constructed by the CGI 6 or the Servlet 6 program using the web server 7.
회원 및 정보관리를 위해 DBMS(3)를 이용하며 메일교환서비스를 제공하기 위하여 메일서버(2)를 이용한다.DBMS (3) is used for member and information management, and mail server (2) is used to provide mail exchange service.
웹브라우저(4) 사용자가 보안메일시스템(1)을 사용하기 위해서는 우선 보안메일시스템(1)에 회원으로 가입을 해야 한다. 웹브라우저(4)로 보안메일시스템(1)에 처음 접속을 하면 회원 ID와 Password를 입력(S2)하라는 화면이 뜨며 회원ID와 Password가 없을 경우 가입신청(S4)을 한다. 회원 가입 시에는 여러 가지 개인정보를 입력하게 되며, 입력 후 신청버튼을 DBMS(3)로 전송되어 관리된다.In order to use the secure mail system 1, a user of the web browser 4 must first register as a member of the secure mail system 1. When accessing the secure mail system (1) for the first time with a web browser (4), a screen for entering a member ID and password (S2) is displayed. If there is no member ID and password, a subscription application (S4) is performed. At the time of membership registration, various personal information is inputted, and after input, the application button is transmitted to the DBMS (3) and managed.
성공적으로 회원에 가입하게 되면 보안메일을 사용할 수 있게 된다. 보안메일은 일반메일과 동일하게 서비스를 제공하며, 암호화메일서비스를 제공한다.Once you have successfully registered, you will be able to use secure mail. Secure Mail provides services like regular mail and provides encrypted mail service.
웹브라우저(4) 사용자는 메일보내기 서비스(C2)를 이용할 것인가 또는 메일보기 서비스(C6)를 이용할 것인가를 선택하게 된다. 메일보내기 서비스를 이용할 경우 회원은 우선 웹브라우저(4)를 통해 메일을 작성(S8)하게 된다. 작성된 메일은 웹서버(7)로 전송되어 보안서비스를 사용할 것인가를 결정한다. 보안서비스를 사용할 경우 암호화메일(C5)을 선택하게 된다.The user of the web browser 4 selects whether to use the mail sending service C2 or the mail viewing service C6. In the case of using the mail sending service, a member first writes a mail through the web browser 4 (S8). The created mail is sent to the web server 7 to decide whether to use a security service. When using the security service, you select the encrypted mail (C5).
암호화메일은 작성되어진 메일에 암호화를 수행하는 것이다.Encrypted mail is to encrypt encrypted mail.
이렇게 작성되어진 메일은 메일서버(4)로 전송(S12)되며 메일서버는 외부의 메일서버와도 메일을 교환할 수 있어 보안메일시스템(1)의 내부 회원만이 아니라 여러 사람과 메일을 교환할 수 있다.The mail thus created is transmitted to the mail server 4 (S12), and the mail server can exchange mail with an external mail server, so that mail can be exchanged not only with internal members of the secure mail system 1, but also with several people. Can be.
메일서버(4)로 전송된 메일은 수신자에 의해서 확인되며 수신자는 메일보기 서비스(C6)를 통해서 수신한 메일을 확인할 수 있다.The mail sent to the mail server 4 is confirmed by the recipient, and the recipient can check the mail received through the mail viewing service C6.
수신한 메일은 수신자에게 사전에 약속된 암호를 입력할 것을 요구하며, 이 암호와 일치하는 것을 입력하는 자 만이 이 메일을 읽어볼 수 있다.Received mail requires the recipient to enter a pre-promised password, and only those who type the same password can read it.
본 발명의 효과는 인터넷상에서 웹을 통하여 안전하게 전자메일을 교환할 수 있도록 하는 것이다. 현재 개인의 프라이버시 보호문제가 중요하게 대두되고 있으며, 인터넷상에서도 일반 정보공유 차원이 아닌 다양한 서비스가 제공되므로 이러한 정보보호의 중요성이 커지고 있다.The effect of the present invention is to enable secure exchange of e-mail over the web on the Internet. Currently, the issue of protecting personal privacy is important, and the importance of such information protection is increasing because various services are provided on the Internet rather than general information sharing.
그러나 정보보호의 개념이 어려워 일반 사용자가 쉽게 접근하기 어렵기 때문에 웹을 통한 편리한 사용자 환경과 보안 환경을 제공해 줌으로써 이러한 요구를 충족시킬 수 있게 된다.However, since the concept of information security is difficult to access easily by general users, it is possible to satisfy these demands by providing a convenient user environment and security environment through the web.
