The secret management of the Korea Military is one of the most significant operation. But the present method of the Korea Military requires much manpower and time, also the range of an object of administration become wider. In this study, We look into an instance of KIDA's 'The Secret Management System Construction Project' which was the first case to incorporate RFID in secret management system. From this instance, We analyze the effect of RFID on security operation in terms of the efficiency, accuracy and usability of security administration. We also present expected problems and possible solutions when it is extended to the field unit.

Ministry of National Defense made has set a standard regulations and detail to classify the revision of the military security and the plan to adjust or use those secrets. Moreover, the confidential management system with online secret process is operated by it. However, the study for management plan of stored secret data in these systems should be urgently required because the current regulation of military headquarter is different from present military situation so that it is not applicable up to now. This paper is focused on the Defense Ammunition Information Systems to find the proper way to deal with the secret data of the Defense Information Systems. The purpose is to describe the management plan for the secret data consistent with the current situation of the Military by study for the secret classification and case study. Therefore limitations are considered and solutions are finally suggested in this paper.

A established military security tast based on existing manual and off-line needs the change and development to support effective and systematic task performance according to environment change of informational and scientific project in the military. Therefore this study suggests to set up the standard model of the defense integrated security system to automate and informationize major defense security task based on actual and problem in the area of major defense of security task and case analysis of these in America, England and other countries. The standard model consist of unit systems were made up integrated security system, security management system, man entrance system, vehicle entrance system, high-tech guard system, terror prevention system and the security accident analysis system, and this suggested model based on possible technology and system. If this model is apply to each real military unit, we will expect the development of defense security.

Medical information is an important personal information for patients, and it must be protected. In particular, when medical personnel approach electronic medical records, authentication for enhanced security is essential. However, the existing public certificate-based certification model did not reflect the security characteristics of the electronic medical record(EMR) due to problems such as personal key management and authority delegation. In this study, we propose a fingerprint recognition-based authentication model with enhanced security to solve problems in the approach of the existing electronic medical record system. The proposed authentication model is an EMR system based on fingerprint recognition using PEMS (Private-key Escrow Management Server), which is applied with the private key commission protocol and the private key withdrawal protocol, enabling the problem of personal key management and authority delegation to be resolved at source. The performance experiment of the proposed certification model confirmed that the performance time was improved compared to the existing public certificate-based authentication, and the user's convenience was increased by recognizing fingerprints by replacing the electronic signature password.

The randomization of scalar multiplication in ECC is one of the fundamental concepts in defense methods against side-channel attacks. This paper proposes a countermeasure against simple and differential power analysis attacks through randomizing the transformed m-ary method based on a random m-ary receding algorithm. The proposed method requires an additional computational load compared to the standard m-ary method, yet the power consumption is independent of the secret key. Accordingly, since computational tracks using random window width can resist against SPA and DPA, the proposed countermeasure can improve the security for smart cards.

Today each country in the world goes beyond the narrow concept of national security that was limited to national defense and ideology and are entering multi-dimensional global system mainly based on economic profits. Nevertheless, conflicts between nations due to religious and ideological reasons have brought unprecedentedly intense disputes Security services for head of states have been an important national mission in every era and society. However, they are becoming a main target for assassination and attacks by terrorists. Attacks on the head of state and other VIPs can cause aftermath ranging from war to conflict situation, political crisis, and economic loss. Therefore this study aims to draw insights by comparing protective security units of Korea, the U.S., and Japan which have different legal basis and sociocultural characteristics. Especially in South Korea, which faces difficult diplomatic stance due to the tension with North Korea and relationship with other countries such as the U.S., China, and Russia as well as polarization between classes, generations, regions, and ideologies, cohesion among members of society has weakened and hatred toward the head of state has been brought, which emphasizes the important of national security services. Therefore the study of protective security units and its operation by comparison between neighboring countries will be able to bring insights on the promotion of the security service.
