Enhanced encryption for light weight data in a multi-cloud system

Abstract

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.
