초록

최근 인터넷 게시판의 실명 및 익명 사용에 대한 논쟁은 주요 이슈가 되고 있다. 실명을 사용할 경우 자유로운 토론 및 프라이버시 침해할 우려가 있는 반면에, 익명을 사용하는 경우에 있어서는 악성 댓글 폭력이라든지, 존재하지 않는 허위 사실 유포 등의 인터넷의 역기능이 나타날 수 있다. 따라서 본 논문에서는 SSO의 기술 중 하나인 XML 토큰 방식을 사용하여 개인정보의 분산을 막고 단일 로그인이 가능하게 하였고 토큰 발급 시 가상 아이디와 경로구성을 통해 익명성 및 조건부 추적이 가능한 익명 게시판을 제안 하였다. 성능분석 결과 접속자 수에 따른 인증시간에서 그룹 서명 방식을 사용한 익명 게시판은 평균 응답 속도가 0.72초, 제안하는 방식은 0.18초를 나타내었다. 즉 인증시간에서 4~5배 정도 빠른 응답 속도를 보였다. 또한 제안하는 시스템은 단일 인증을 제공하고 사용자가 서명을 하지 않아도 되기 때문에 사용자 편의성에서 월등히 뛰어나며, 익명 게시판 환경에서의 사용자 편의성은 제안하는 시스템이 더 적합함을 알 수가 있었다.

The argument related to the use of real and anonymous names on the Internet bulletin board has recently become a main issue. When using real names, it is possible to violate free discussion and privacy. Also, when using anonymous names, it is possible to have the reverse function of the Internet in regard to the use of malicious replies or the distribution of false ideas. Therefore, this paper has made it possible to prevent the spread of the user's personal information and execute the single log-in process by using the XML-token method which is one of the SSO technologies. Also, by issuing virtual IDs and forming the path when establishing tokens, the anonymous bulletin board which provides anonymity with a conditional tracing process has been suggested. After analyzing the performance of visitor numbers at authentication time, the anonymous bulletin board based on the group signature method showed the average response rate of 0.72 seconds, 0.18 seconds, which was suggested scheme. In the authentication time 4-5 times faster response speed, respectively. Also, since the suggested system does not have to provide a single authentication process or make the user provide his or her signature, the level of user's convenience seems to be much higher. Such a result shows that the system suggested on the anonymous bulletin board has a more appropriate level of user's convenience.
