Growing importance of online security on certification, many of the web-related security technology introduced day by day. Especially, using smart certificate (USIM) is recognized as one of the most safe and convenient method for the security of public certificate. The purpose of this study is to find the factors that affect the Intention of switching to smart certificate for the general public who use public certificate service. Based on migration theory, this study determined the relationship between pull factors, push factors and mooring factors which can affect the intention of switching to smart certificate. To empirically analyze the proposed hypothesis, the statistical analysis were conducted based on the response from 350 public certificate service users using SPSS 22.0 and Smart PLS 2.0. The results of this study can be summarized as follows. First, system quality, one of the pull factors has positive influence on perceived ease of use. On the other hand, the other pull factor, service quality has positive influence on both perceived ease of use and perceived usefulness. Second, push factors, user experience and information security awareness have positive influence on perceived ease of use only. Third, mooring factor, switching cost does not have influence on switching intention while perceived usefulness has positive influence on. The results of this research can be used for whom has interest to the switching intention of public certificate service for online security and provide the proper understanding about smart certificate service mechanism.

사용자가 스마트 기기 및 개인 PC를 통해 정보 시스템에 접근하기 위해서는 사용자 인증을 통한 정당한 사용자임을 증명해야한다. 이때 사용되는 사용자 인증 기술에는 ID/PW 기반 인증기술, OTP(One-Time-Password), 인증서, 보안카드, 지문인식 등 다양하다. 그 중에서 ID/PW 기반 인증기술은 사용자에게 익숙하지만 무작위 대입공격, 키로깅, 사전공격 등의 패스워드 공격에 취약하며 이러한 공격에 대응하기 위해 사용자는 복잡한 패스워드 조합 규정에 따라 주기적으로 패스워드를 변경해야한다. 본 논문에서는 기존 ID/PW 기반 인증 기술보다 보안성을 높이면서 패스워드를 사용하지 않고 스마트폰의 USIM 정보를 이용한 사용자 인증 시스템을 설계 및 구현하였다.
