Recently, financial institutes and industrial companies are adopted to security token such as OTP, smart card, and USB authentication token and so on for secure system management and user authentication. However, some research institutes have been introduced security weaknesses and problems in security tokens. Therefore, in this paper, we analyses of security functions and security requirements in security token performed by analyses of standardization documents, trends, security problems, attack methods for security tokens. Finally, we propose a CC v.3.1 based security token protection profile.

주민등록번호는 주민생활의 편익 증진과 행정사무의 적정한 처리를 목적으로 도입되었으나 인터넷의 발달과 함께 관행적이고 무분별하게 사용되어 왔다. 수집된 주민등록번호가 해킹 등의 유출사고로 명의도용 등 범죄에 악용될 우려가 커지자 이를 근본적으로 해결하기 위하여 2011년 방송통신위원회는 인터넷상 주민등록번호 수집 이용을 제한하는 법 제도적 정책을 추진하였다. 정보통신망법이 개정되어 주민등록번호의 사용이 제한되면서 사업자에게 본인확인, 연령확인 등 법률의무의 이행이나 고객의 분쟁조정 등 목적을 위해 주민등록번호를 대체할 본인확인수단이 필요하게 되었다. 본 논문에서는 주민등록번호를 이용자가 입력하지 않으며 보편적으로 사용하고 있는 인프라를 이용하고 단순한 입력정보의 변경을 통해 본인확인을 할 수 있는 방안을 제안한다.

This paper focuses on how the protection of information security incident is effective in via Information security awareness when conducting information security activities of enterprises. Research models have theorized that the information security activity and the information security awareness will reduce the incidence of information security. The general characteristics of analysis targets have been carried out in the frequency analysis, and the reliability of the measuring tool has been utilized to calculate the coefficient of Cronbach's information protection. Evidence has been demonstrated regarding the relationship between information security activities and information security awareness and information security incidents.

I study on the security organization for the chief of state in North and South Korea. The paper, purporting to analyze security system in comparative prospectives, comprise four chapters. Chapter I Which sets out purpose, scope and method, is followed by Chapter II , dealing largely with the power structure on The Socialist Constitution of Democratic People's Republic of Korea, the protection organization and security activities for the chief of state in North Korea. Chapter III concerns the security environment - terrorist groups, firearms, explosives, suspects, movements of hostile countries and orthers - and the protection organization on The Presidential Security Service for the president in South Korea, culminating in projection of certain problem area. It is followed by concluding observation made in Chapter IV. To be operated security systems effectively, these need to be regulated according to a protective scale, function, authority of a existing.

Analyzed about a matter and requirements to intimidate security of ubiquitous and home network threatening various security for personal information protection in ubiquitous home networks at these papers, and studied. Got authentication procedures and verification procedures acid user approach to be reasonable through designs to the home security gateway which strengthened a security function in the outsides, and strengthened protection of a home network. Also, execute a DoS, DDoS, IP Spoofing attack protective at home network security gateways proved, and security regarding an external denial of service attack was performed, and confirmed. Strengthen appliances and security regarding a user, and confirm a defense regarding an external attack like DoS, DDoS, IP Spoofing, and present a home network security model of this paper to the plans that can strengthen personal information protection in ubiquitous home networks in ubiquitous home networks through experiment.

Internet network routing system is used to prevent spread and distribution of malicious data traffic. This study is based on analysis of diagnostic weakness structure in the network security domain. We propose an improved integrated multi-level protection domain for in the internal route of groupware. This paper's protection domain is designed to handle the malicious data traffic in the groupware and finally leads to lighten the load of data traffic and improve network security in the groupware. Infrastructure of protection domain is transformed into five-stage blocking domain from two or three-stage blocking. Filtering and protections are executed for the entire server at the gateway level and internet traffic route ensures differentiated protection by dividing into five-stage. Five-stage multi-level network security domain's malicious data traffic protection performance is better than former one. In this paper, we use a trust evaluation metric for measuring the security domain's performance and suggested algorithm.

The reversal of a silicon chip to find out its security structure is common and possible at the present time. Thanks to reversing, it is possible to use a probing attack to obtain useful information such as personal information or a cryptographic key. For this reason, security-related blocks such as DES (Data Encryption Standard), AES (Advanced Encryption Standard), and RSA (Rivest Shamir Adleman) engines should be located in the lower layer of the chip to guard against a probing attack; in this regard, the addition of a silicon-surface-protection layer onto the chip surface is a crucial protective measure. But, for manufacturers, the implementation of an additional silicon layer is burdensome, because the addition of just one layer to a chip significantly increases the overall production cost; furthermore, the chip size is increased due to the bulk of the secure logic part and routing area of the silicon protection layer. To resolve this issue, this paper proposes a practical silicon-surface-protection method using a metal layer that increases the security level of the chip while minimizing its size and cost. The proposed method uses a shift register for the alternation and variation of the metal-layer data, and the inter-connection area is removed to minimize the size and cost of the chip in a more extensive manner than related methods.

In this paper, the information security requirements in the mobile ad-hoc network(MANET) are presented, and the algorithm to establish the protection node(gateway) is proposed to prevent the distributed denial of service(DDoS). The information security technology and security threats in the MANET are presented, and protection node is decided to minimize the total cost through the sending nodes and receiving nodes by way of protection node. To set up the protection node, the minimization algorithms of maximum cost and the average cost between the protection node and receiving nodes are compared with the optimal solutions, in which optimal solution is found out by all enumeration method. From the results, the total cost between the sending and receiving nodes is minimized under the average cost minimization algorithm rather than the using of the maximum cost.

This study researched into the method that allows only the certified user and computational engineer to possibly use network resources and computing resources by implementing the system of the intensified certification and security based on LDAP(Lightweight Directory Access Protocol) directory service, that copes with incapacitation in security program due to making the security program forcibly installed, and that can correctly track down the industrial-technology exporter along with applying the user-based security policy through inter-working with the existing method for the protection of industrial technology. Through this study, the intensified method for the protection of industrial technology can be embodied by implementing the integrated infra system through strengthening the existing system of managing the protection of industrial technology, and through supplementing vulnerability to the method for the protection of industrial technology.

Memory protection has been researched for decades for program execution protection. ARM recently developed a newhardware security feature to protect memory that was applied to real hardware. However, there are not many hardware withhardware memory protection feature and research has not been actively conducted yet. We perform diagnostics on howandhow it works on real hardware, and on security, with a new hardware memory protection feature, named 'Pointer Authentication Code'. Through this research, it will be possible to find out the direction, use, and security of future hardware security technologies and apply to the program.
