기술발전에 따라 원자력시설에 사용되는 장비가 아날로그 시스템에서 디지털 시스템으로 변경되는 추세이다. 컴퓨터와 디지털시스템의 비율이 증가함에 따라 원자력시설은 사이버 위협에 노출되었다. 그 결과 사이버보안에 대한 관심이 높아지고 사이버 공격으로부터 시스템을 보호해야 한다는 인식의 변화가 생겼다. 국내 규제기관에서 발행한 KINAC/RS-015는 필수디지털자산에 대해 101가지 사이버보안 통제항목을 제시하였지만 디지털자산의 특성을 고려하지 않은 일반적인 항목이다. 모든 사이버보안 통제항목을 필수디지털자산에 적용하는 것은 많은 작업량과 효율성을 떨어뜨린다. 본 논문에서는 필수디지털자산의 특성을 파악하고 적절한 보안조치항목을 제시함으로써 효과적인 사이버 보안 통제항목 적용을 제안한다.

As evidenced through rapidly growing digital devices and information, digital authentication is becoming ever more critical, especially considering the complex and prevalent digital accounts we are using every day. Also, digital authentication is apt to consistent digital security application. In this sense, digital security quality and usability can be enhanced by developing a mechanism for efficient digital authentication. In this paper, a mechanism of efficient digital authentication called T-TIME is introduced in order to alleviate issues dealing with secure and user friendly authentication across ever- growing digital devices and information. Touch Signal generation time difference is utilized for T-TIME as a mediation mechanism that enhances the security quality by confusing others unlike other graphical password mechanisms which are using spatial information. Hence, digital authentication by using T-TIME can be a good way of enhancing security quality and usability.

Trade rules in service and digital sectors mainly focus on reducing regulatory uncertainties by improving transparency and minimizing unnecessary requirements. Recognizing the importance of digital trade rules and trade in information and communication technology (ICT) sectors, governments worldwide have rapidly adopted and expanded rules on free flow of data, personal data protection, electronic authentication, and cybersecurity. On the other hand, advances in technology have led governments to face multiple threats related to cybersecurity, intellectual property (including that related to source code and algorithms), and unauthorized access to proprietary information of their suppliers. This study presents digital trade rules related to digital security emphasizing cybersecurity, source code, and ICT products that use cryptography in different trade agreements. Additionally, it introduces various approaches that major countries are taking to both address digital security issues and seek balance between security enhancement and trade liberalization.

사이버공간 속 디지털문화의 융복합 윤리교육은 개인정보, 저작권 등 특정 영역에만 국한되고 있어 사이버 공간의 사용자인 디지털 네이티브들이 소통하고 공유하고 교류하는 사이버공간 속 정보수용능력과 정보 제공능력에 관한 교육은 미비한 상태이다. 이로 인해 정보보안의 중요성을 인지하지 못하고 타인의 개인정보를 남용하는 역기능이 최근 사회문제로 대두 되고 있다. 본 연구에서는 사이버공간에서 가장 많이 정보를 소통하고 교류하는 디지털네티즌들 가운데 대학교 1~2학년 학생들을 대상으로 디지털 리터러시 교육을 실시한 후 이들이 정보보안 인식의 변화를 조사하였다. 이를 바탕으로 디지털 문화사회회에 필요한 디지털 리터러시 교육의 체계적 양성의 근원적인 대책의 마련하고자 한다.

This study is to develop digital leadership in a field of national defense. Today, korean society is facing the crisis of national security. But national defense leadership is not show in the circumstance of national security crisis. As you know, national defense leadership is a process that make use of influence. Which means it converges people's interest and demands well and also show people the right vision of national defense and make them to comply the policy about national security. Because of the environmental change, our national defense leadership is having a new turning point. First, international order, which is under post-cold war, raises possibility of guarantee of peace and security in international society but also, cause the increase of multiple uncertainty and small size troubles in security circumstance. In addition, Korean society is rushing into democratization and localization period by success in peaceful change of political power went through about three times. The issue of political neutralization of military is stepping into settlement but still, negative inheritance of old military regime is worrying about it. In this situation, we can't expect rise in estimation about the importance of security and military's reason for being. So, military have to give their concern to not only internal maintenance of order and control and growth of soldiers but also developing external leadership to strength influence to society and military's the reason for being. So for these alternative I'm suggesting a digital leadership of national defense which fits digital era. This digital leadership is the leadership which can accept and understand digital technology and lead the digital organization. To construct digital national defense we need a practical leadership. The leadership has to be digital leadership with digital competence that can direct vision of digital national defense and carry out the policy. A leader who ha s digital leadership can lead the digital society. The ultimate key to construct digital government, digital corporate and digital citizen depends on digital leader with digital mind. To be more specific, digital leadership has network leadership, next generation leadership, knowledge driven management leadership, innovation oriented leadership. A leader with this kind of leadership is the real person with digital leadership. From now on, to rise this, we have to build up human resource development strategy and develop educational training program.

Information security is becoming a more important factor in distribution of digital contents. Generally, illegal facsimile of high-quality multimedia products such as DVDs, MP3s and AACs is possible without damaging quality. Thus, the illegal distribution of duplicated contents on the Web is causing digital content providers great economic loss. Therefore, a study of security and efficient distribution of digital contents is required. The most important issues in the design of a digital content distribution system are user convenience, execution speed and security. In this study, we designed a digital contents distribution system that uses web caching technology and encryption/decryption techniques in hierarchical structures. We propose a digital content distribution system that improves user convenience, security and execution speed. The superior performance of the proposed system has been proven in the tests. The results of experiment show that the developed system has improved the security of DC without decreasing process speed.
