Conclusion is like below. First, as a private security area's mutual relationship and development device, it is necessary to bring up corresponding-terror expert. Second, a privatized corresponding-terror research center is necessary. Third, the importance of privatization's role for the corresponding-terror prevention law establishment. It is considered that a diversified examination research that can minimize a violation of human rights by bringing up various corresponding-terror expert, paradigm shift of workers related security area, and construct corresponding- terror education equipment as well as education content, it is not a special group's authority, should be continued by a following research. Academical area of terrorism's construction is necessary. You need to approach by private initiatively boldly with the academic world as an active mutual cooperation politically, culturally, socially, internationally, etc, rather than developing national institute initiatively. Also, in a following research, an academical research about a correlation of crime, war, terror should be done deeply, variously. It is necessary to establish an academic foundation of terror study.

According to the current legislation in Korea, some of national R&D reports cannot be disclosed or registered, when they need external security or the interested parties require them to be classified for a certain period of time. Therefore, there are some effects on the collection and circulation of information about R&D reports. Since those closed national R&D reports are the important outcomes from national R&D projects, they should be properly open, circulated and used by the public, when the reasons for closing those reports are removed. This study examines the present condition of the closure system of national R&D reports, and proposes a plan for collecting and utilizing the closed national R&D reports at the national level.

E-Commerce, characterized by the exchange of message, occurs between individuals, organizations, or both. A critical promotion factor of e-Commerce is message authentication, the procedure that allows communicating parties to verify the received messages are authentic. It consists of message unforgery, message non-repudiation, message unalteration, and origin authentication. It is possible to perform message authentication by the use of public key encryption. PGP(Pretty Good Privacy) based on X.400 MHS(Message Handling System) and PKC(Public Key Cryptosystem) makes extensive use of message exchange. In this paper we propose, design and implement NMAP(New Message Authentication Protocol), an applied public information based encryption system to solve the message authentication problem inherent in public key encryption such as X.400 protocol and PGP protocol and were to cope with the verification of NMAP using fuzzy integral. This system is expected to be use in the promotion of the e-Commerce and can perform a non-interactive authentication service.

By the development of IT, most business has been processed on the IT solution-based servers has increased Therefore, the importance of security of the server is highlighted. And the need for password management server efficient and safe is raised. There is a need to change at least 8 characters to mix the numbers and letters and password change passwords on a regular basis, you need a password for each system account is set in a different way, but the continuation of the system there is a tendency to password problems occur problems caused by the limits of the introduction of human resources and introduction basis occurs. The password management feature, though it is expensive is partially providing integrated access control solutions at home and abroad, there is a drawback that stresses the traffic on the server. Future, we conducted a study of password management solutions for the server of the server is determined IT transformation trend of non-IT field to accelerate, is continuously increasing it accordingly.

IoT(Internet of Things) has become a major issue as new type of convergence technology, expending existing of USNs(Ubiquitous Sensor Networks), NFC(Near Field Communication), and M2M(Machine to Machine). The IoT technology defines as a networking for things, which can establish intelligent links collaboratively for sensing networking and processing between each other without human intervention. The purpose of this study is to investigate to forecast the future distribution changes and orientation of contribution of distribution industry on IoT and to provide the implication of distribution changes. To become a global market leader, IoT requires much more development of core technology of IoT for distribution industry, new service creation and try to use a market-based demand side strategy to create markets. So, to become a global leader in distribution industry, this study results show that first of all establishment of standardization of IoT, privacy safeguards, security issues, stability and value were more important than others. The research findings suggest that the development goals of IoT should strive to boost the creation of a global leader in distribution industry and convenience to consider consumers' demands as the most important thing.

Devising a secure authenticated key agreement (AKA) protocol for two entities communicating over an open network is a matter of current research. McCullagh et al. proposed a new two-party identity-based AKA protocol supporting both key escrow and key escrow-less property instantiated by either in a single domain or over two distinct domains. In this paper, we show that their protocol over two distinct domains suffers from masquerading attack and therefore does not satisfy the claimed security. The attack is made possible due to the lack of sufficient authentication of entity and integrity assurance in the protocol. We then propose an efficient verifiable key agreement protocol by including signature primitive in the authentication procedure to solve the problem of McCullagh et al.'s protocol.

The explosive growth in wireless networking increasingly urges the demand to support mobility within the Internet which is what Mobile-IP aims to provide. Because the transmission of signals through open-air s easy to be attacked, it is important to provide secure transmission for mobile users and make them responsible for what they have done in networks. Although IETF provides a secret-key based security mechanism, those mechanisms suffer from scalability, efficiency and non-repudiation service problem. The proposed mechanism uses public-key based authentication optimizing the performance. It includes non-repudiation service on the side of mobile for airtight security in wireless network. The simulation results show that the proposed authentication reduces the total registration time. It especially minimizes the computation cost on the side of the mobile node and solves the power problem. In practice, the proposed authentication is feasible with reasonable performance and security service in macro mobility that Mobile-IP is intended to solve.

Recently, virtualization is becoming the critical issue in the cloud computing due to its advantages of resource utilization and consolidation. In order to efficiently use virtualization services, several issues should be taken into account, including data reliability, security, and performance. In particular, a high write bandwidth on the virtual machine must be guaranteed to provide fast responsiveness to users. In this study, we implemented a way of visualizing comparison results between the block write pattern of KVM-based virtual machine and that of the real machine. Our final objective is to propose an optimized virtualization environment that enables to accelerate the disk write bandwidth.
