모바일 단말은 다양한 서비스와 컨텐츠를 지원하지만, 최근 모바일 악성코드의 급증으로 인하여 사용자에게 개인 정보 유출, 요금 과다 등의 피해를 초래하고 있다. 특히, 안드로이드 플랫폼은 오픈 플랫폼으로서 공격자들이 악성코드를 배포하기에 유리한 환경을 가지고 있어 시그니처/행위기반 분석방법을 통한 악성코드 탐지 연구가 활발히 진행되고 있다. 본 논문에서는 안드로이드 플랫폼에서 악성코드를 탐지하기 위한 Feature를 선정하였다. 또한 SVM(Support Vector Machine) 기계학습 알고리즘을 통하여 악성코드 탐지성능을 분석하고 우수성을 검증하였다.

In this paper, we investigate the security issues of the Android platform which dominates the global market of smart mobile devices. The current permission model for Android security is not powerful and has two problems. One is the coarse-grained relationship between permissions and methods which require them. The other is that mobile users do not have rights to control the permissions of the application. To solve these problems, we propose MacDroid which can control the platform's resources for accessing installed applications. Users can control the application's behavior via MacDroid's policy. We have divided the permission set into method units. The results of the performance test using a pure Android platform show that our proposed scheme can improve security within a short time.

As the new variation malicious codes of android platform are drastically increasing, the preparation plan and response is needed. We proposed a high-interaction client honeypot that applied to the android platform. We designed flow for the system. Application plan and the function was analyze. Each detail module was optimized in the Android platform. The system is equipped with the advantage of the high-interaction client honeypot of PC environment. Because the management and storage server was separated it is more flexible and expanded.

We forecast that the scale of mobile market will be large scale according to the twenty million times of smart phone's user is arrived. The type of software development is being transferred into mobile-based App. or cloud computing-based service from web-based software. Currently both Google's android and Apple's IOS are known for two prominent platforms. Existing modeling techniques cannot be applied into the case of mobile application which is executed those platforms. Therefore, we suggest a modeling technique that is customized existing modeling techniques into android-based software development. That is, we propose an analysis and design techniques which are needed into android-based mobile smart environment.

This paper presents a technique for an Android mobile device to best utilize its surrounding external display device such as high-definition TV, in order to overcome the size and resolution limitation of the small LCD in the mobile device. Unlike current techniques that simply expand the LCD screen image to an external large display, our technique dynamically changes the resolution adapting to capability of the external display. And, the original screen become a remote controller.

In this study, we developed mobile contents and mobile learning system for learning of english presentation based on Android platform. First, the application including contents transfer system which enables contents run on Android platform was developed for learning of English presentation. Second, presentation contents which will be applied on the application were manufactured. The contents developed in this study are for learning English presentations. The contents are classified into two parts; Part 1 is for basic English presentations, and Part 2 is for advanced English presentations. Each part is made up with 9 units, and each unit is composed differently by topics. The number of whole chapter for both parts is 51. We analyzed the questionnaire responses with respect to UI satisfaction and satisfaction of the learning experience. The UI satisfaction results showed that 85% of the participants were satisfied at an ordinary or higher level with our system. And The satisfaction of the learning experience results showed that 95% of the participants were satisfied at the ordinary or higher level with our system.

최근 모바일 플랫폼으로 부상하고 있는 Google사의 안드로이드는 2008년 9월에 안드로이드의 첫 번째 공식 SDK 버전 1.0을 출시하여 현재(2010년 3월) SDK 버전 2.1까지 출시하였다. 안드로이드 플랫폼에서 블루투스 디바이스를 제어하기 위해 개발자들은 Android SDK의 Bluetooth API가 필요하게 되는데 이는 1.0~1.6버전까지는 지원 되지 않고 2.0 버전부터 공개가 되었다. 하지만 문제점은 안드로이드 2.0이 발표되기 이전에 나왔던 대부분의 안드로이드 단말은 2.0 업데이트 펌웨어를 현재까지도 지원하지 않고 있다는 것에 있다. Bluetooth API는 Android SDK 2.0 버전 이상에서만 사용 가능하기 때문에 개발자들이 개발한 블루투스 어플리케이션의 최소 펌웨어 버전 요구사항이 2.0 이상 일 수밖에 없는 것이다. 이 연구에서는 안드로이드 1.x 버전에서 사용될 수 있는 블루투스 API의 개발에 대해 알아보고자 한다.

Expand the market because the size of the huge funds administered by the conversion of over-the-air digital TV broadcasts in the current situation is likely to be reduced due to the influence of the media over-the-air broadcasts new paid media, digital cable TV and IPTV new mobile TV as a new growth engineis required. Broadcasting system to increase the supply and demand of the module from the ATSC-M/H DMB business existing in the domestic over-the-air broadcasters, has seen significant achievements in sleep technology with the introduction is expected. ATSC-M/H does not require a separate frequency allocation for mobile services does not interfere with the existing ATSC system simulcast, which can be performed on Android mobile handsets American-style mobile broadcast reception module to develop should. This paper is to design the software modules in the broadcasting module embedded systems that are applied on the Android platform, broadcasting from mobile handsets to see.
