본 논문은 대규모 네트워크 온라인 게임에서 게임 진행 중에 발생할 수 있는 부하를 최소화 할 수 있고 추후 확장이 용이한 온라인 게임 서버의 구조에 대해 설명한다. 본 논문에서 설명하는 게임 서버는 게임 서버가 제공해야 하는 기능별로 로그인 서버, 존 서버, 사용자 관리 서버, 그리고 DB 에이전트로 구성된다. 각 서버들은 상호 연관관계를 최소화하여 어느 한 서버에 고장이 발생하였을 때 전체 게임에 발생할 수 있는 문제를 최소화 할 수 있고 추후 확장이 용이한 구조이다.

CEP(Complex Event Processing) is a technique to find complex event pattern in a massive information system. Based on CEP technique, an abuse pattern monitoring method has been developed to provide an real-time detection. In the method, the events occurred by game-play are observed to be against the rules using CEP. User abuse patterns are pre-registered in CEP engine. And CEP engine monitors user abuse after aggregating the game data transferred by game logging server. This article provides the performance analysis results of the abuse pattern monitoring method using real game DB. We results that the method proposed in previous study is effective to monitor abusing users.

본 논문에서 신입생 OT, 워크샵과 같이 대규모 인원이 모였을 때 아이스브레이킹을 목적으로 진행할 수 있는 게임을 기획하고자 한다. 이러한 유형의 게임이 갖추어야 할 가장 중요한 요소는 많은 인원과 쉬운 규칙이다. 100명 이상의 많은 인원이 동시에 플레이할 수 있어야 하고 그 인원이 게임에 대한 이해도와 경험이 모두 달라도 즐길 수 있을 만큼 쉬운 규칙이어야 한다. 또한, 오프라인 보드게임은 온라인으로 게임을 했을 때 보다 비용절감과 친밀감을 형성하는데 도움이 된다.

This study analyzed the importance of user activity, communication between users and identity establishment by growth and change of player's character through users' communication structure and then it classified such an importance into activity by group, dealings, information sharing, duel and strategy performance. It also looked into the plans to revitalize smooth social relationship and suggested for users to behave with responsibility in virtual society. In the virtual space where thousands of people connect and interact with each other every day, users find out their identities through human relationship with others proceeding solo story. What is more important is that users consider virtual space as a society and feel collective responsibility on words and behavior against others.

In the market of First Person Shooter (FPS) games, Massively Multi-player Online FPS games (MMOFPS) like 'PlanetSide 2' have been popular recently. Dead reckoning has been widely used in order to mitigate the network traffic overload for the game server with hundreds or thousands of people. This paper proposes the efficient analytical method to calculate the tolerable threshold angle of moving direction, which is one of the most important factors for character status updating when dead reckoning is used in MMOFPS games. The experimental results with game testers shows that the proposed method minimizes the position error for character moving and provides natural direction updates of characters.

Along with the development of mobile technology, mobile game has undergone a change from downloadable game to network game, where a large number of users connect to server and play real-time game with a mobile phone. In order to develop these mobile network games economically, a proper, suitable game engine is needed. This study proposes the result of design and implementation of RWMMO-GE(Realtime Wireless Massively Multiplayer Online RPG Game Engine) that is used to develop a mobile network game. The structure of RWMMO-GE, which is the research result of this study, consists of major components such as Network/Client Module, Object Module, Map Tool, Script Editor, and Character Editor. The characteristics of the multiplayer mobile game developed by this engine is that a large number of players can play real-time game in a single map, which implies a possibility of a new business model in this area. This research is a result of the RWMMO-GE supported by 2006 IT Excellent Technology Support Project(No:A1300-0601-0125) of IITA(Institute Information Technology Advancement).

온라인 게임은 가장 성공적인 인터넷 서비스 중 하나로서 빠른 속도로 성장해 왔다. 그러나 게임을 대상으로 하는 다양한 공격들이 있었고 그로 인해 많은 정상 사용자들 및 게임서비스 회사에 피해가 발생함에 따라, 온라인 게임 서비스를 보호하기 위한 다양한 기법들이 연구되어 왔다. 실제로 대규모 이용자들이 접속하는 PC 게임들의 경우, 게임 클라이언트단, 네트워크 단, 서버 단 각 구간별로 다양한 보안 기법들이 개발되어 적용되어 왔다. 이 중, 게임 클라이언트는 사용자 및 해커 쪽에서 손쉽게 접근이 가능하기 때문에 공격에 쉽게 노출되어 있어 신뢰하기 어려운 구간이었다. 더불어, 게임 클라이언트 단에 강력한 보안을 적용할 경우 성능저하가 발생하기 때문에 상용 게임보안 솔루션에 의해 프로세스 및 메모리 보호를 받는 등 역공학 방지 기법 및 난독화 기법 정도만을 최소한으로 적용하고, 그 외에는 대부분의 탐지 및 차단 기법들을 네트워크 단 및 서버 단에 적용하는 것이 일반화 되어 있다. 하지만, 최근 하드웨어의 지원을 받아 클라이언트 단의 성능저하를 최소화 하면서도, 게임 클라이언트를 TEE (Trusted Execution Environment)에서 안전하게 실행할 수 있는 기술들이 등장하면서, 게임 클라이언트 단의 보안기술이 다시 주목받고 있다. 본 논문에서는 메모리 변조 공격 및 게임프로세스에 인젝션 공격을 하는 게임해킹 기법들에 대응하기 위하여 Intel에서 발표한 새로운 하드웨어 보안 기술인 Intel SGX(Software Guard Extensions)를 적용하는 방안에 대해 소개한다. Intel SGX를 적용하여 게임프로그램의 프로세스를 보호할 경우 코드와 데이터의 무결성 및 기밀성을 보장하며 실행시킬 수 있기 때문에, 온라인게임보안 발전에 상당히 기여할 수 있을 것으로 기대된다.

This study aims to investigate on the perception types of online games and their characteristics. In Study 1, perceptions of online games were researched through Q methodology. From the results, the perceptions of online games are classified into four types: 'Online Game is an Obstacle of Study'; 'Online Game is Just a Game'; 'Online Game is a Stain in Life'; 'Online Game is Vaguely Bad'. Each perception type has different characteristics in terms of perception of harmfulness of games, determination of the core of game problems, and perception of a parent-child relationship. In Study 2, the distribution and characteristics of each perception type were researched through an online survey. The results show differences in an attitude to online game using features and regulations as well as in demographic parameters such as sex and age. This study holds its significance in identifying the differences between perception types of online game and providing a basic study for policy making of healthy game culture.

The market size of online games has been rapidly growing as well as the behaviors of online gaming users have been changed. Online games are different from the traditional video games, because they permit players to interact each other during playing games. Today online gaming is a part of everyday life and social interaction has an impact on online gaming behaviors. Social interaction does not only have a positive impact on online game behaviors, but it also has a negative impact on them such as excessive online game usage. Previous research has a limitation to consider social interaction as a comprehensive concept. In order to fill the gap, we explore the factors of social interaction influencing on excessive online game usage. After reviewing previous literature, this study chooses three factors of social interaction such as escaping loneliness, expanding online social bridging capital, and reinforcing offline social bonding capital. The findings show that all of three factors of social interaction positively affect the excessive online game usage.
