云存储提供了随时随地访问数据的灵活性，同时提供了经济效益和可伸缩性。然而，云存储缺乏管理数据来源的能力。数据来源描述了一段特定数据是如何产生的。它对于事件后调查至关重要，广泛用于医疗保健、科学合作、法医分析和法律诉讼。数据来源需要得到保护，因为它可能泄露敏感数据的私人信息，而云服务提供商不保证存储在分散地理位置的数据的机密性。本文提出了一种在提供加密搜索的同时保护云中的数据来源的方案。
Cloud storage offers the flexibility of accessing data from anywhere at any time while providing economical benefits and scalability. However, cloud stores lack the ability to manage data provenance. Data provenance describes how a particular piece of data has been produced. It is vital for a post-incident investigation, widely used in healthcare, scientific collaboration, forensic analysis and legal proceedings. Data provenance needs to be secured since it may reveal private information about the sensitive data while the cloud service provider does not guarantee confidentiality of the data stored in dispersed geographical locations. This paper proposes a scheme to secure data provenance in the cloud while offering the encrypted search.
