  • 네트워크 및 컴퓨팅 기술의 발달로 데이터를 위탁 저장하고 이를 언제어디서든 다양한 단말로 처리 할 수 있는 클라우드컴퓨팅서비스가 활성화되고 있다. 특히 클라우드컴퓨팅 서비스 중 DaaS가 널리 사용되고 있다. 하지만, 위탁 저장된 데이터베이스에 신체 정보라던가 개인의 민감한 정보가 암호화 없이 저장된다면 서버에 저장된 데이터를 데이터 소유주의 동의 없이 공격자 및 비윤리적인 서버관리자가 열람할 수 있다는 보안 문제점이 있어 위탁 저장된 데이터베이스의 암호화가 필요하다. 하지만 기존에 사용되고 있는 암호화 알고리즘으로 암호화된 데이터를 안전하게 검색하기 위해선 암호화 데이터를 전부 데이터 소유자의 단말기에 내려 받고 전부 복호화해서 검색해야 하기에 데이터를 위탁 저장하는 의미가 퇴색된다. 이와 같은 문제를 해결하기위해 검색 가능한 암호시스템(Searchable Encryption System)이 등장하게 되었다. 하지만 기존의 검색가능 암호 시스템은 같은 키워드를 검색하기위해 생성된 트랩도어가 동일한 형태를 가지게 된다. 수많은 검색 쿼리들이 위탁저장소에 전송되며, 저장소의 관리자는 쿼리를 통해 키워드를 유추하고, 쿼리를 통해 사용자가 어떤 데이터를 저장하고 검색하는지 학습이 가능하기 때문이다. 따라서 본 논문은 동일한 사용자가 같은 키워드를 검색하더라도 매번 다른 트랩도어가 생성되도록 하여 비윤리적인 서버관리자가 검색 쿼리를 통해 검색 내용 및 데이터를 유추할 수 없도록 하는 일회용 트랩도어를 이용한 검색가능 암호 시스템을 제안한다.

  • The cloud services market is growing rapidly from the on-premises environment to the cloud computing environment and the domestic cloud software market in Korea is expected to grow at a CAGR of around 15%. In Korea, research teams are providing open cloud platforms using open source software under the government taking the initiative, which intends to enhance the reliability and functionality of open cloud platforms, provide users with a world-class open cloud platform-based and developer-friendly environment that is managed on heterogeneous cloud infrastructure and supported by full-lifecycle management of application software. In this paper, we propose a method to utilize CaaS in the open cloud platform, through incorporating the platform with the container orchestration platform. Finally, by providing users with the application runtime and container runtime, it presents how the two platforms can coexist and cooperate in the same ecosystem.

  • In the trend of digital transformation and the increase in non-face-to-face services triggered by the Fourth Industrial Revolution, the demand for cloud computing services is being sharply stimulated. Currently, the cloud is being introduced in various industrial sectors including public, IT, and finance, and the manufacturing industry is also adopting the cloud to secure future sustainability and is promoting innovation through smart manufacturing. However, it has been found that there are constraints in the adoption of cloud by manufacturing companies due to concerns about security. Existing studies that have identified cloud security risks have been limited to presenting general cloud security risks or technical security risks rather than focusing on the manufacturing industry. Therefore, this study aimed to identify cloud security risks in the manufacturing industry based on the actual concerns in the field. For this, expert interviews and literature research were conducted to newly identify cloud security risks in the manufacturing industry, and the adequacy and urgency of the selected security risks were verified through surveys. Based on this study, if a cloud security management system for the manufacturing industry is designed in the future, it is expected that the adoption of cloud in the manufacturing industry will be more activated.
