A Systematic Review of Studies on Cyber Physical System Security
Peiyuan Dong,Yue Han,Xiaobo Guo,Feng Xie 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.1
Cyber-Physical System (CPS) is a system of systems which integrates physical system with cyber capability in order to improve the physical performance [1]. So far, it is being widely applied in areas closely related to national economy and people’s daily lives. Therefore, CPS security problems have drawn a global attention and an appropriate risk assessment for CPS is in urgent need. According to the researches and discussions in recent years, we believe that most researchers have already established a comprehensive understanding about CPS. This paper systematically introduced CPS’s conception, development and applications assisted. In addition, concerning about its aspects of safety and security, we also analyzed CPS’s risks and new requirements as an up-to-date technique brings. We elaborate the existing work and propose a research focus that has not been paid enough attention to, and proposed a security framework for CPS. At last, after providing a classic modeling and simulation method of CPS, we bring forward a new idea for accessing the experimental results into existing systems.

A Framework for Analyzing Anonymous Network Topology
Tianbo Lu,Shixian Du,Yang Li,Peiyuan Dong,Xiaoyan Zhang 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.4
Nowadays, Internet privacy becomes more and more important and sensitive, and has been one of the latest buzz words to hit the Internet world. In response to protect the privacy of Internet users, a variety of privacy enhancing technologies (PETs) have emerged. As one of privacy enhancing technologies, anonymous communication has been extensively studied from various aspects by researchers. Node churn is frequent in anonymous network, which make it difficult to maintain a stable network topology, therefore it is necessary to get more insight into the overall anonymous network topology. In this work, in order to better grasp the present situation of research, we investigate existing organizations and universities which study anonymous communication from the perspective of network topology, and related projects. Then we survey related papers to anonymous communication published in recent years, which focus on the analysis of node selection (especially in the Tor). In addition, we present a framework of anonymous communication network topology, and a visual illustration of this analysis that shows the progression of the research of network topology and node discovery in anonymous communication. Finally, some related problems and follow-up study are presented to be studied deeply in future.
