개인의 신원정보 보호에 대한 중요성이 높아지면서 개인이 직접 자신의 신원정보를 관리하고 데이터의 주권을 신원정보 소유자에게 부여하는 자기주권 신원 시스템에 대한 관심이 높아지고 있다. 자기주권 신원 시스템 내에서 개인은 스스로 자신을 식별할 수 있는 분산 식별자(DID: decentralized identifier)를 생성하고 분산 식별자 별 개인의 자격을 증명해주는 자격증명(VC: verifiable credentials) 정보를 발급받아 개인이 보유하며 자격증명의 검증을 요구하는 검증자에게 선택적으로 자격증명 정보를 제시한다. 개인의 프라이버시를 보호하기 위해 개인의 자격증명을 제시할 때 신원정보의 실제 데이터는 감추고 자격증명의 유효성은 입증시키는 영지식 증명의 개념을 적용하고 있다. 본 논문에서는 영지식 증명 기술을 살펴보고 하이퍼레저 인디(Hyperledger Indy) 기반 자기주권 신원 시스템에서 영지식 증명 기술 도입 예를 보인다.

본 논문에서는 스트림 암호 구현 시 하드웨어 설계가 용이한 고속 자기 상관기와 이를 이용한 개선된 키 수열 동기 방식을 제안하였다. 제안 방식은 키 수열 동기시 잡음이 무선 채널에서도 동기를 유지할 수 있는 고속, 고신뢰도 초기 키 수열 동기 방식이며, 기존 방식보다 복잡도를 크게 줄 여서 하드웨어 구현이 용이하도록 하였다.

In this paper, we research on the personal information protection system in smart-phone based on mobile environment. This paper proposes the enhanced personal location privacy mechanism in location-based service environment of a smart phone operating system(iOS, Android) for the relevant regulations on location-based protection and utilization. Also, the result verified that possibility on a self-control mechanism of the personal information protection system's subject in the window platform throughout the experiment. Therefore, this study have drew a method that user positively can cope with a protection of personal location information by having a user's self-control method in the system under development or done by illegal location-based service providers and illegal application developer.

SCADA system is a computer system that monitors and controls the national infrastructure or industrial process including transportation facilities, water treatment and distribution, electrical power transmission and distribution, and gas pipelines. The SCADA system has been operated in a closed network, but it changes to open network as information and communication technology is developed rapidly. As the way of connecting with outside user extends, the possibility of exploitation of vulnerability of SCADA system gets high. The methodology to protect the possible huge damage caused by malicious user should be developed. In this paper, we proposed anomaly detection based intrusion detection methodology by estimating self-similarity of SCADA system.

This study aims to present policy implications by analyzing information security behavior factors of internet users. The research model, based on PMT and UTAUT2, consists of perceived threat, severity, social influence, self-efficacy, experience and habits, PC and privacy behaviors, security behaviors on new services and set demographic characteristics, use places of internet, use of paid products, and experiences of accident as moderate variables to analyze the effect on security behavior. The results showed that perceived severity, self-efficacy significantly influenced on experience and habits, and experience and habits and self-efficacy had a high influence on PC and privacy behavior. Also, PC and privacy behaviors have a high impact on security behavior of new services. Age, income, use of paid products, and experience of accidents have a moderating effects on security behaviors. The results of this study are expected to help policy decision making to improve the level of information security of internet users.

In February 2014 Korean Bar Association has amended Professional Ethics Code as to stipulate attorney's duty to protect personal information. While existing Korean law and Professional Ethics Code has made attorney to keep client's confidential information, attorney's newly promulgated obligation has its meaning in that personal information of subject other than client is not protected through confidentiality rules, given that confidentiality obligation is interpreted to protect only client's information relating to representation. Moreover, duty to protect personal information deals with not only disclosure and use of information, which confidentiality rules is about, but also collection and retention process, access to and correction and care of information and even destruction of information. Amid unprecedented theft of personal data in several national banks and other serious leakage reported recently, this paper is going to contemplate the scope and application of the duty to protect personal information with hope to contribute to starting discussion on it.
