In 2013, the small retailer organized support service, which commenced in 2009, has been expanding its place in the policy by transforming into a small retailer cooperating support service. This support service supports two main sides. One of them is strengthening the financial aspects of the scale by organizing the small retailers in order to make the distribution efficient. The second is improving the management and enhancing the efficiency through visitation education. This research focuses on studying the effects of the visitation education which is one of the two aspects of small retailers support service. Empirical analysis on the effects of the visitation education's quality on the loyalty of support service and business performance was performed in detail by dividing the structure of the companies into chain form and combined form of small retailers. According to the results of the analysis, the visitation education's quality positively affected the support service's loyalty without any restrictions on the structures of the retailers. However in the business performances, the visitation education's quality only showed positive effects on the combined form of small retailers. Therefore, it is implied that in order to continuously receive support program by increasing the loyalty of the retailers, the quality of the visitation education must be increased and the retailer support service need to be considering the structure of the companies in order to improve small retailer's business performance.

공인인증서는 10여 년 간 국내 인터넷 뱅킹이나 전자상거래에서 본인인증 수단으로 긴요하게 이용되어 왔다. 그러나 공인인증서는 처음 발급받았던 저장매체에서 사용이 가능하며, 재발급 시에 기존 인증서를 폐기한 후 새로운 인증서를 발급받아야 하는 불편함이 있다. 2010년 행정안전부에서는 2013년부터 하드디스크 내 공인인증서 저장을 금지한다는 방안을 발표하였다. 이에 따라 사용자들은 공인인증서를 이동형 저장매체에 저장한 후 사용이 가능하게 되어 이동형 저장매체의 중요성이 높아지게 되었으며, 분실 위험에 노출되어 있는 이동형 저장매체가 없을 시에도 안전하게 인증서를 사용할 수 있는 시스템이 필요하게 되었다. 본 논문에서는 위와 같은 불편함을 줄이고자 기존에 발급받았던 인증서를 토대로 경량화 된 일회용 인증서를 발급받음으로써 안전하고 효율적인 결제가 가능하도록 하는 시스템을 설계 및 구현하였다.

공인인증서의 사용은 꾸준히 증가하고 있으나 증가하는 사용량에 비례하여 하드디스크에 저장된 공인인증서 해킹으로 인한 피해 사례가 증가하고 있다. 이에 따라 정부는 하드디스크 내 공인인증서 저장을 금지하고 이동형 저장매체에 저장하도록 하는 방침을 내놓았다. 또한 모바일 클라우드 컴퓨팅 환경에서는 중앙의 스토리지에 데이터가 저장되기 때문에 공인인증서를 중앙 스토리지에 저장하는 것은 매우 위험한 일이다. 이러한 방침으로 인해 앞으로 USB 메모리 및 스마트폰과 같은 이동형 저장매체에 대한 중요성이 높아질 것이며, 분실 위험이 높은 USB 메모리 및 스마트폰의 특징에 따라 인증서가 저장된 저장매체 없이도 인증서를 사용할 수 있는 방안이 필요하게 될 것이다. 본 논문은 일회용 인증서에 대한 요구사항 분석 및 형식을 설계하고, PKI 인증서를 기반으로 경량화된 일회용 인증서를 발급받아 인증서를 사용할 수 있도록 하였다. 또한 모바일 클라우드 컴퓨팅 환경에서 일회용 인증서를 이용한 권한 관리 기술을 제안하여 안전성과 효율성을 제공하도록 하였다.

We have various e-commerce like on-line banking, stock trading, shopping using a PC or SmartPhone. In e-commerce, two parties use the certificate for identification and non-repudiation but, the attack on the certificate user steadily has been increasing since 2005. The most of hacking is stealing the public certificate and private key files. After hacking, the stolen public certificate and private key file is used on e-commerce to fraud. Generally, the private key file is encrypted and saved only with the user's password, and an encrypted private key file can be used after decrypted with user password. If a password is exposed to hackers, hacker decrypt the encrypted private key file, and uses it. For this reason, the hacker attacks user equipment in a various way like installing Trojan's horse to take over the user's certificate and private key file. In this paper, I propose the management method to secure private key of PKI using One Time Password certification technique. As a result, even if the encrypted private key file is exposed outside, the user's private key is kept safely.

Organization is increasing the authorizing process to use public certificate and bio information. Certificate, has evolved to be able to parallel distributes the bio authentication and portable bio-authentication device. Authentication using an individual's PC and smart devices continue to generalize, while convenience for authentication is increased by comparison Study on cooperation with the security at the network level's a weak situation. If ask authentication method through the cooperation of the public certificate and bio information work with current network access control, there is a possibility to develop a more powerful security policy. by cooperation weaknesses against vulnerable personal authentication techniques on security token in a reliable and secure personal authentication techniques, such as bio-recognition, Bio Information for identification and to prevent exposing a methodology suggest to validate whether or not to carry out in this paper. In addition, organize the scenario that can work with the 802.1x network authentication method, and presented a proposal aimed at realization.
