The purpose of this study was to investigate the application of fashion-related web sites and their evaluation. 76 college students major in fashion design were surveyed and the evaluation criteria were classified into five categories such as the accuracy/reliability, the design of a picture, the ease of application, the communication/security, and additional services. The results of this study were as follows: 1. College students used web sites mostly to search for fashion trend information from magazine and fashion information sites. 2. While the media site was excellent in the evaluation criteria such as the accuracy/reliability, the design of a picture and the communication/security, the fashion information site was excellent in the evaluation criteria such as the accuracy/reliability, communication/ security and additional services. 3. The media site and the fashion information site generally ranked high and the fashion brand site ranked low in most evaluation items. 4. By the results of ANOVA, 12 items showed significant differences out of the total 19 items. 5. Out of the total evaluation items, the design of a picture ranked highest and the external link function ranked lowest.

In the recent IT industry, security has established itself as the factor to be considered the most in the software development. It goes without saying that security is the critical factor for the development of information security products. In the evaluation of the information security products, the security is assured by the security architecture requirement (ADV_ARC). However, the Absence of the systematic software security architecture process makes it difficult to guarantee the security quality consistently even though they are evaluated based on common criteria. In this paper, we propose a way to ensure a consistent security quality applying the software security framework in BSIMM.

Objective of this study is to design and implement security system based on intrusion tolerance technology for the improvement of dependability in defense system. In order to do so, I identify and extract core technologies through the research and analysis into characteristics, structures, main functions, and technologies of intrusion tolerance architecture. And I accomplish a design of security system through the redundant system based on these core technologies. To implement and verify intrusion tolerance system, I chose 'wargame system' as a subjected system, and accomplished 'Wargame Intrusion Tolerance System' and verified security required functions through a performance test. By applying showed security system into the development of application software based on intrusion tolerance, systematic and efficient system could be developed. Also applying 'WITDS' can solve the current security problems, and this will be basic model for design of security architecture in the federation system after.

In this paper we challenge the user Authentication using KerberosV5 authentication protocol in WPKI environment. This paper is the security structure that defined in a WAP forum and security and watches all kinds of password related technology related to the existing authentication system. It looks up weakness point on security with a problem on the design that uses wireless public key based structure and transmission hierarchical security back of a WAP forum, and a server client holds for user authentication of an application layer all and all, and it provides one counterproposal. Therefore, We offer authentication way solution that connected X.509 V3 with using WIM for complement an authentication protocol KerberosV5 and its disadvantages.

This paper design a role-based access control model that can resolves the complicated problems of access control requirements. In this paper, we designed an access control model which can control a permission making use up role-based access control, can guard the confidentiality, integrity and availability of information and can control illegal information flow. The designed access control model can protect resources from unauthorized accesses based on the role, multi-level security policies of security level, integrity level and ownership.

In Black hat USA 2014, a hacking method to infer the password entry of smartphone or smartpad with google glass in distance is presented. In this paper, we design the secure keypad to protect the key stroke inference attacks with google glass which has unique layout ensuring same input entry but different input value.

In this paper, we propose an architecture design of military operation system utilizing cellular networks. The main contribution of this paper is to provide a cost-effective military operation solution for ground forces, which is based on IT(information technology). By employing the cellular phones of officers' and non-commissioned officers' as the tools of operational communication, the proposed system can be constructed in the minimum duration and be built on the four components: command and control system, gateway, security system, and terminal(cell phone). This system is most effective for the warfare of limited area, but the effectiveness does not decrease under the total war covering the whole land of Korea. For the environmental change of near future, expanded architecture is also provided to utilize the functionalities of smart phones.

Computing and Networking technologies are rapidly developed. A lot of hacking events are occurring. As a result, people have a interesting for security in these days. Network security systems have come to be widely used in our networks. But, objective testing method to evaluate network sorority system is not established. Therefore we have difficulties that select a system. In this paper, we investigate evaluation methods for network sorority systems(Firewall, IDS, IPS etc.) and, design a evaluation tool for network security systems.

In this paper, we consider a joint beamforming and jamming design to enhance physical layer security against potential multiple eavesdroppers in a multiple-input and single-output cellular broadcast channel. With perfect channel state information at the base station, we propose various design approaches to improve the secrecy of the target user. Among the proposed approaches, the combined beamforming of maximum ratio transmission and zero-forcing transmission with a combination of maximum ratio jamming and zero-forcing jamming (MRT + ZFT with MRJ + ZFJ) shows the best security performance because it utilizes the full transmit antenna dimensions for beamforming and jamming with an efficient power allocation. The simulation results show that the secrecy rate of this particular proposed approach is better than the rates of the considered conventional approaches with quality-of-service and outage probability constraints.
