The electronic transactions over the Internet are growing across the world recently. There have been a lot of identity theft incidents during these online transactions nowaday. Therefore, a high level of identity proofing shall be carried out when using online services to deal with these matter. To prevent this kind of incident, i-PIN was introduced in Korea, which is used as an Internet Personal Identification Number. The i-PIN is designated to provide an online identification of the Internet users. As such, the unique identification numbers are provided to the internet service providers. This paper is to analyze the capabilities that the i-PIN provides, to propose the assurance security model for i-PIN. Furthermore, the security analysis results are presented. The result of this paper can be applicable to improve the applicabilities of the i-PIN.

As the status of public certificates expired due to the recent revision of the Electronic Signature Act, electronic signature-based public certificates were also lost in the means of replacing resident registration numbers(RRN). As a result, public certification institutions have recently been designated by the Korea Communications Commission as identity verification service providers through a review of the designation of personal identity proofing agency based on alternative means of RRN. However, unlike existing RRN replacements such as i-PIN, mobile phones, and credit cards, the personal identity proofing process for applicants for certificates is different from existing alternatives. The proposed method shows that it is possible to protect users' personal information and provide universal, reasonable, and safe identification services by applying improvements to electronic signature-based personal identity proofing services.

Recently, the application of personal proofing service based on social security number(SSN) replacement means for verifying identity in non-face-to-face transactions is increasing. In this paper, we propose a method of applying differentiated personal proofing service on whether identity verification is necessary in the online service provided by ISP and if it is appropriate to apply a certain level of assurance. By analyzing the requirements related to personal proofing required by current ISPs, we analyze the risks for each of the requirements and propose a method of applying differentiated personal proofing service according to the level of identity assurance guarantee to minimize the risks. In applying the proposed method to online service provision, it is possible to reduce user's unnecessary authentication cost by minimizing the application of personal proofing service based on alternative means, and to help protect user personal information by minimizing excessively collected personal information.

Currently, online means of replacing resident registration numbers(RRN) include I-Pin, mobile phone, credit card, MyPin, and general-purpose certificate. In order to issue alternative means based on the RRN, it must be designated through the designation review by the Korea Communications Commission(KCC) through a designation review by personal proofing agency and be subject to annual management. However, the criteria for designation and follow-up of the designation of the personal proofing agency carried out by KCC have been used in 2010 without revision, and there are problems that do not conform to the evaluation standards of various alternative means. Therefore, in this paper, we propose a method for improving the designation criteria and management system of the personal proofing service agency. The proposed method analyzes the characteristics of the alternative identification-based personal proofing service and proposes a follow-up management standard that can appropriately evaluate the analyzed characteristics and improves the designation criteria according to the emergence of new alternatives. Through the proposed method, it can be seen that it is possible to strengthen the safety of the personal proofing service based on the alternative means of RRN provided online and face-to-face and to protect the user's personal information.

A resident registration number is used to confirm and prove his/her identity in a government/non-governmental agency. It is a essential requirement to become the registered member on internet website in Korea. It is serious problem that the resident registration number and name are outflowed in internet and misused by others. So the MIC(Ministry of Information and Communication) in Korea plans and operates the identification system using I-PIN that integrate 5 alternative methods of resident registration number. In this paper, we analyze the problem about the method of 5 I-PIN services and show the security analysis on the implementation vulnerabilities of I-PIN services. we also analyze 17 websites that provides identification system using I-PIN. Finally, we analyze the overall problem of I-PIN service and propose the countermeasure about the problem.

주민번호대체수단은 주민번호를 대체하기 위한 본인확인정보로서, 5 개의 민간기업이 운영하는 민간 i-PIN과 행정안전부가 운영하는 공공 i-PIN이 서비스를 제공하고 있다. 하지만 주민번호대체수단이 더욱 활성화되기 위해서는 기존에 제시된 보안성, 편의성 문제를 해결해야 한다. 본 논문은 신원 선택기를 추가하여, i-PIN의 프로토콜을 변경하지 않는 범위 이내에서 i-PIN의 단점으로 지적되는 로그인 번거로움, i-PIN 사이트 기억 문제, 피싱을 비롯한 보안 문제를 해결하는 방안을 제시하였다. 제안하는 방법은 사용자가 가입한 i-PIN 제공자에 접근하는 단계, i-PIN 제공자에 id 와 비밀번호를 입력하는 단계를 없애고, 신원 선택기를 통해 사용할 신원 정보를 선택하는 것만으로 처리되도록 하였다. 본 기술은 ETRI 에서 개발중인 전자 ID 지갑 솔루션을 통해 구현되었으며, 해당 서비스는 2009 년 중에 민간 i-PIN 제공자를 통해 시범 도입될 예정이다.

최근 개인의 정보보호에 관한 관심이 높아져 가고 있으며 자신의 정보보호를 위해 스마트카드가 사용되어지고 있는 추세이다. 기존의 스마트카드는 카드 주체를 확인하는 과정으로 PIN(Personal Identity number) 제출을 요구한다. 본 논문에서 이러한 사용자의 확인 과정에 사용되는 PIN 대신 생체인식 중 서명을 스마트카드에 저장하였으며 이를 이용하여 사용자 인증을 위한 시스템에 대해 연구하였다. 본 논문은 스마트카드의 패스워드의 분실이나 강제에 의한 도용을 방지하고 사용자에 좀더 익숙하고 안전한 서비스를 보장 받게 될 것이다.

Recently, We have many private information leakage cases through internet which cause social problems and it is impossible to change or update the leaked information, it is also used to the third crime such as identity theft, internet fraud. Hackers are interested in stealing private information for making money, in this point private information leakage problems are constantly increased hereafter. In this paper, I surveyed the authorization model on site registration which is currently used in Korea, and the problem of collecting personal identification number, I proposed policy model of useless method of private information, especially leaked information can not be used anymore in internet.

AAA(Authentication, Authorization, Accounting) is the service that offers authentication, authorization, and accounting method, and every terminal that accesses the network requires this AAA service. The authentication process of a mobile terminal is as follows: a mobile phone accesses an authentication server in a home network via the authentication service in an external network, which receives the authentication result. And, for the home authentication server to offer secure service, a unique key is distributed for the secure communication between the external agent and the user, the external agent and the home authentication server, and the user and the home authentication server. This paper discusses and proposes the key distribution for secure communication among external authentication servers when a mobile terminal travels to an external network. As the proposed method does not require the home authentication server to reissue another authentication when a user travels to other external networks, it reduces the overload in the home authentication server. It can also distribute a PIN-driven key.
