The development of IT technology and breakthrough of the network and the wired network, wireless network boundaries disappear and wired and wireless integrated service environment is the advent in online game environment. However, the wired and wireless integrated service environment appropriate security technology is still inactive, wired and wireless integration environment due to the characteristic as well as security threats wired network and security threats in wireless networks should be considered. Therefore, This wired and wireless integrated environment has been considering studied various, Among them wired and wireless environment considering the lightweight of ID-based authentication and key management has been in progress. In recent, Moon et al. pervasive environment in authentication and ID-based key management protocol is proposed. However, Moon et al.'s scheme is use the ID-based public-key approach to decreased the amount of computation. However, pairing by using a technique similar to the existing public key scheme can represent the amount of computation. Therefore, In this paper the way of Moon etc in security vulnerability analysis.

Online platforms recently expanded their connectivity through an authing service. The growth of authing services enabled consumers to enjoy easy log in access without exerting extra effort. However, multiple points of access increases the security vulnerability of platform ecosystems. Despite the importance of balancing authing service and security, only a few studies examined platform connectivity. This study examines the optimal level of authing service of a platform and how authing strategies impact participants in a platform ecosystem. We used a game-theoretic approach to analyze security problems associated with authing services provided by online platforms for consumers and other linked platforms. The main findings are as follows: 1) the decreased expected loss of consumers will increase the number of players who participate in the platform; 2) linked platforms offer strong benefits from consumers involved in an authing service; 3) the main platform will increase its effort level, which includes security cost and checking of linked platform's security if the expected loss of the consumers is low. Our study contributes to the literature on the relationship between technology convenience and security risk and provides guidelines on authing strategies to platform managers.

According to increasing activities in the cyberspace, various on-line services through the Internet have been offered, and many recent studies on the Internet services such as instant messenger, game, and portal site have been performed to evaluate quality of these services. However researches on weblog(blog), a personal online journal for general public consumption, have not been performed much yet. Therefore, we have conducted an empirical study on investigating the structural relationships among weblog service quality, satisfaction and loyalty in this study. After reviewing the related literatures, we have suggested a model for evaluating the service quality of weblog, wb-SERVQUAL(weblog-SERVQUAL), by modifying the conventional SERVQUAL model based on characteristics of weblog. Structural Equation Model(SEM) has been used to analyze the structural relationships among service quality of weblog, user satisfaction and customer loyalty. Managerial implications are also suggested for managing the weblog sites in conclusion.

MMORPG makes up 25.9% of domestic market share in game industry, and it has become increasingly fierce in competition. Game developer and publisher make every effort to build customer e-loyalty to sustain their competitiveness. Thus, this paper examines the determinants of e-loyalty that reflect the features of MMORPG such as intensive and real-time interactivity. For this purpose, we selected interactivity, sense of community, reward and fun as the key antecedents of e-loyalty based on the extensive review of previous researches related to online game and Internet service usage. A total of 202 responses were used for analysis and the research results are as follow. The findings show that interactivity, sense of community and reward influence significantly on fun, then fun is positively related to e-loyalty. Also, interactivity and reward are proven to have a positive influence on sense of community, and sense of community mediates the effect of interactivity and reward on fun.

According to KISA, many people play smartphone games. stress relieving, time is the reason to beat. Attempts to combine mobile games and education in the Korean game market are continuing. Studies have shown that using commercial games for education can be effective. Also, researches for activation educational games are increasing. Creating educational games requires a lot of time and money. Due to the nature of mobile games, the service is often terminated without updating. If you are able to acquire a naturally educational part while playing mobile games, you will see the effect of one pair of fun and education, both at once. We analyzed the education factors of the game with 'Real Farm' which is a simulation farm game. We focused on analyzing information acquisition and utilization part through indirect experience which is characteristic of simulation and examined educational factors based on design elements of educational game. This can signal the positive aspects of the game and the educational content of existing games. If you use smartphones as a pedagogy, you can expect a positive perception of games and an increase in the average life expectancy of mobile games.

During wireless network operations, adaptive power control is an effective way to enhance the network performance. In this paper, a new online power control scheme is proposed based on the evolutionary game theory. To converge a desirable network equilibrium, the proposed scheme adaptively adjusts a transmit power level in a distributed online manner. With a simulation study, we demonstrate that the proposed scheme improves network performance under widely diverse network environments.

본 논문에서는 메타버스 공간에서 패션 아이템 판매에 있어서 필수적이라 할 수 있는 온라인 가상 피팅 기술을 동작 인식 전용 디바이스가 아닌 일반 스마트폰 카메라를 활용하여 구현하는 기술을 제안한다. 가상 피팅 기술을 구현하기 위해서는 딥러닝 기법을 활용하여 입력 영상을 분석하고, 분석 결과를 토대로 인체의 전체 자세를 추정하며, 인체 사이즈의 근사값을 추출하는 과정들이 수행되어야 하는데, 현재의 스마트폰 컴퓨팅 환경은 이를 수행하기에 충분한 연산 성능을 가지지 못한다는 문제점을 가진다. 본 논문에서는 높은 비용이 요구되는 고부하 연산을 클라우드 서버를 통해 수행하는 서버 기반 프레임워크를 도입하여, 낮은 성능의 스마트폰으로도 고성능 연산이 가능한 서비스 구조를 확보하고 이를 통해 휴대성 높은 증강현실 기반의 가상 피팅 기술을 구현한다. 본 논문의 성과를 통해 메타버스 상거래의 활성화와 메타버스 본연의 의미에 충실한 가상 월드 구축에 기여할 것이라 기대한다.

Korean Game industry, especially MMORPG(Massively Multiplayer Online Game) has been rapidly expanding in these days. But As game industry is growing, lots of online game security incidents have also been increasing and getting prevailing. One of the most critical security incidents is 'Game Bots', which are programs to play MMORPG instead of human players. If player let the game bots play for them, they can get a lot of benefic game elements (experience points, items, etc.) without any effort, and it is considered unfair to other players. Plenty of game companies try to prevent bots, but it does not work well. In this paper, we propose a behavior pattern model for detecting bots. We analyzed behaviors of human players as well as bots and identified six game features to build the model to differentiate game bots from human players. Based on these features, we made a Naive Bayesian classifier to reasoning the game bot or not. To evaluated our method, we used 10 game bot data and 6 human Player data. As a result, we classify Game bot and human player with 88% accuracy.
