Abstract

Cloud Computing Environment provides users with a blue print of IT Utopia with virtualization; unbounded computing power and data storage free from the cost and the responsibility of maintenance for the IT resources. But, there are several issues to be addressed for the Cloud Computing Environment to be realized as the blue print because users cannot control the IT resources provided by the Cloud Computing Environment but can only use them. One of the issues is how to secure and to trust data in the Cloud Computing Environment. In this paper, an efficient and practical trust assurance of data with provenance in Cloud Computing Environment.

가상화를 통해 원하는 만큼의 컴퓨팅 파워와 데이터 저장 공간을 제공하면서도 관련된 IT자원의 유지보수 비용과 관리에서는 사용자를 해방시켜주는 많은 장점에도 불구하고, 클라우드 컴퓨팅이 가까운 미래에 실질적인 서비스로 자리잡고 활성화를 위해서는 먼저 넘어야 할 장벽들이 있다. 즉, 사용자의 제어 너머에 있는 클라우드 컴퓨팅 환경이 IT서비스와 인프라에 대해 사용자에게는 이용권만을 주기 때문에 비롯되는 여러 문제들이 생기게 된다. 가장 큰 이슈 중의 하나는 클라우드에 저장되는 정보의 보호 및 신뢰성 확보이다. 본 논문에서는 provenance 통한 클라우드 상의 데이터 신뢰확보에 대한 효과적이고 유용한 해법을 제안한다.
