Cloud storage is a cloud deployment that allows the setup of in-house data storage facilities by organizations. Cloud computing's popularity allows mobile devices to store/retrieve personal data from anywhere at any time. Consequently, the problem of data security in the mobile cloud is becoming increasingly serious and prevents further mobile cloud development. In order to improve cloud security, substantial studies have been conducted. However, most of them are not applicable for mobile cloud since mobile devices particularly have limited computing resources and power. This article proposes an enhanced Attribute-based encryption scheme for lightweight distributed cloud data. Multiple cloud computing provides storage assistance in a single heterogeneous environment. The proposed method ensures confidentiality, secure data storage, and file sharing through the multi-cloud environment. In comparison to traditional schemes, quantitative results suggest the feasibility of the proposed mechanism.

云存储是一种云部署，允许组织设置内部数据存储设施。云计算的普及使移动设备可以随时随地存储/检索个人数据。因此，移动云中的数据安全性问题变得越来越严重，并阻止了进一步的移动云发展。为了提高云安全性，已经进行了大量研究。但是，由于移动设备尤其具有有限的计算资源和能力，因此它们中的大多数不适用于移动云。本文提出了一种针对轻量级分布式云数据的增强的基于属性的加密方案。多个云计算可在单个异构环境中提供存储帮助。提出的方法可确保机密性，安全的数据存储，和通过多云环境共享文件。与传统方案相比，定量结果表明了该机制的可行性。
