  • By using smartphones more generally, people's lives become more convenient. However, many people complain of stress caused by the use of smartphones, further, the tendencies to reject it are appearing. In this paper, new conceptual word, antismart-resistance consciousness gained by experience before and after introduction of smart devices - is newly proposed as a research variable. In addition, we have studied to identify the relationship affecting continuous use of smartphones with technostress and antismart. To achieve this, a research model and hypotheses were presented and verified by using questionnaires data. The result showed that users who actively embrace innovative technologies were highly tolerant of technostress, whereas knowledge or experience of IT trends did not affect technostress or antismart tendencies.

  • 안드로이드는 스마트폰에서 프로그램을 실행하도록 하는 구글에서 개발한 모바일 전용 운영체제로써 현재 수백만 대의 스마트폰, 태블릿PC에 탑재되어 있다. 안드로이드는 빠른 속도의 웹브라우저, 멀티 태스킹, 클라우드 컴퓨팅 기능, 다른 장치와 쉽게 연결하여서 공유하는 기능 등을 제공하고 있다. 이에 따라 많은 스마트폰 제품들이 안드로이드 운영체제를 탑재하여 출시하고 있으며, 안드로이드는 전 세계 스마트폰 운영체제 점유율의 절반가량을 차지하고 있다. 하지만 안드로이드 운영체제가 많이 사용됨에 따라 그에 따른 안드로이드 악성코드 또한 급격하게 증가하고 있다. 따라서 본 논문에서는 안드로이드 악성코드를 탐지 및 차단할 때 분석 비용을 감소시킬 수 있는 권한정보 관리를 통한 안드로이드 안티바이러스 어플리케이션을 제안한다.

  • In this paper, we present a smart grid monitoring system connected with electric vehicle charging system using anti-islanding method. Electric vehicles can be charged through remote control of smart grid monitoring system and the charging process may be more stable and more efficient by wireless communication between the Local Area Module and End Modules. It is illustrated by some experiments that electric vehicle charging process may not be interrupted without any serious fault even though the islanding phenomena occurred in the grid if the presented monitoring system was applied to the smart grid system.

  • As the popularization of smartphone increases the number of various applications, the number of malicious applications also grows rapidly through the third party App Market or black market. This paper suggests an investigation filter, Androfilter, that detects the fabrication of APK file effectively. Whereas the most of antivirus software uses a separate server to collect, analyze, and update malicious applications, Androfilter assumes Google Play as the trusted party and verifies integrity of an application through a simple query to Google Play. Experiment results show that Androfilter blocks brand new malicious applications that have not been reported yet as well as known malicious applications.

  • With the popularization of smartphones, Social Networking Service (SNS) has become the means of communication for modern people. Due to the nature of the means of communication, SNS generates a variety of archive and preservation evidence. Therefore, it is a major analysis target in terms of digital forensic investigation. An application that provides SNS stores data in a central server or database in a smartphone inside for user convenience. Some applications provide encryption for privacy, which can be anti-forensic in terms of digital forensic investigation. Therefore, the study of the encryption method should be continuously preceded. In this paper, we analyzed two applications that provide SQLite-based database encryption through SQLCipher module. Each database was decrypted and key data was identified.

  • Recently, discussions for the eradication of illegal shooting have been carried out in a socially-oriented way. The government has established comprehensive measures to eradicate cyber sexual violence crimes such as illegal shooting. Although the social interest in illegal shooting has increased, the illegal film shooting case is evolving more and more due to the development of information and communication technology. Applications that can hide confused videos are constantly circulating around the market and community sites. As a result, field investigators and professional analysts are experiencing difficulties in collecting and analyzing evidence. In this paper, we propose an evidence collection and analysis framework for illegal shooting cases in order to give practical help to illegal shooting investigation. We also proposed a system that can detect hidden applications, which is one of the main obstacles in evidence collection and analysis. We developed a detection tool to evaluate the effectiveness of the proposed system and confirmed the feasibility and scalability of the system through experiments using commercially available concealed apps.

  • 현재 가장 높은 점유율을 보이고 있는 스마트 모바일 디바이스 플랫폼인 안드로이드는 바이트코드 기반의 어플리케이션을 동작시킨다. 바이트코드는 특성상 역공학에 취약하여 원본 코드의 노출이나 수정 후 재배포가 쉽게 이루어질 수 있다. 이를 보완하는 방법으로 난독화, 실행압축, 코드 분리, 기타 안티 리버싱 기법 등이 존재하지만, 이런 보호기법을 단독으로 사용하면 그 효과가 높지 않다. 이들은 각각 장단점을 가지고 있는데, 여러 기법을 조합해서 사용하면 보안성을 한층 높일수 있다. 그렇다고 각 기법의 특징을 무시한 채 무작정 사용하게 되면 오히려 어플리케이션의 성능이 낮아지고 크기가 늘어나는 문제가 발생한다. 따라서 보호기법의 정확한 이해와 필요에 맞는 올바른 선택적 사용이 중요하다. 본 논문에서는 지금까지 사용되어 온 안드로이드 어플리케이션 역공학 보호기법의 유형과 특징에 대하여 살펴보고, 보안성을 높이기 위한 올바른 조합과 선택에 대해 고찰한다.

  • 스마트폰이 대중화되면서 안드로이드 애플리케이션의 보안문제가 대두되고 있다. PC환경의 소프트웨어는 개발단계에서부터 시큐어코딩을 통해 안전성을 확보하고 있으나 안드로이드 애플리케이션의 경우는 연구가 더 필요한 상황이다. 본 논문에서는 CWE(Common Weakness Enumeration)의 취약점 분류 체계와 CAPEC(Common Attack Pattern Enumeration and Classification)의 공격 패턴 분류 체계와 CERT(Computer Emergency Response Team)의 취약점 발생 예방을 위한 정책들을 통해 안드로이드 애플리케이션의 최신화된 취약점 목록을 도출하고 카테고리별로 분류하여 취약점을 효율적으로 분석하는 기법을 제안한다.

  • With the explosive growth of smart phones and efficiency, the Android of an open mobile operating system is gradually increasing in the use and the availability. Android systems has proven its availability and stability in the mobile devices, the home appliances's operating systems, the IoT products, and the mechatronics. However, as the usability increases, the malicious code based on Android also increases exponentially. Unlike ordinary PCs, if malicious codes are infiltrated into mobile products, mobile devices can not be used as a lock and can be leaked a large number of personal contacts, and can be lead to unnecessary billing, and can be cause a huge loss of financial services. Therefore, we proposed a method to detect and delete malicious files in real time in order to solve this problem. In this paper, we also designed a method to detect and delete malicious codes in a more effective manner through the process of installing Android-based applications and signature-based malicious code detection method. The method we proposed and designed can effectively detect malicious code in a limited resource environment, such as mobile environments.

  • Due to the widespread use of mobile devices, smartphone penetration and usage rate continue to increase and there is also an increasing amount of data that need to be stored and managed in applications. Therefore, recent applications use mobile databases to store and manage user data. Realm database, developed in 2014, is attracting more attention from developers because of advantages of continuous updating, high speed, low memory usage, simplicity and readability of the code. It also supports an encryption to provide confidentiality and integrity of personal information stored in the database. However, since the encryption can be used as an anti-forensic technique, it is necessary to analyze the encryption and decryption processes provided by Realm Database. In this paper, we analyze the structure of Realm Database and its encryption and decryption process in detail, and analyze an application that supports an encryption to propose the use cases of the Realm Database.
