An efficient and secure data sharing scheme for mobile devices in cloud computing Xiuqing Lu1,2, Zhenkuan Pan1* and Hequn Xian1
Abstract With the development of big data and cloud computing, more and more enterprises prefer to store their data in cloud and share the data among their authorized employees efficiently and securely. So far, many different data sharing schemes in different fields have been proposed. However, sharing sensitive data in cloud still faces some challenges such as achieving data privacy and lightweight operations at resource constrained mobile terminals. Furthermore, most data sharing schemes have no integrity verification mechanism, which would result in wrong computation results for users. To solve the problems, we propose an efficient and secure data sharing scheme for mobile devices in cloud computing. Firstly, the scheme guarantees security and authorized access of shared sensitive data. Secondly, the scheme realizes efficient integrity verification before users share the data to avoid incorrect computation. Finally, the scheme achieves lightweight operations of mobile terminals on both data owner and data requester sides. Keywords: Big data, Security, Integrity, Cloud computing
Introduction With the rapid development of information technology and Internet of Things (IoT), enterprises generate more and more big data, which needs to be stored and processed efficiently and securely. Cloud computing is a developed storage platform and has many advantages including low cost and scalability [1–3]. Therefore, many enterprises and individuals are apt to outsource their data to cloud for storage and sharing with authorized data requesters. For example, in a cloud based health information system, patients upload their health information to cloud for sharing with medical experts to diagnose diseases. Similarly, the manager of an enterprise not only want to store the big data in cloud, but also want to share the data among their authorized employees wherever needed. Outsourcing data for sharing
in cloud not only saves local storage space, but also greatly reduces the cost of enterprises in software purchase and hardware maintenance [4–6]. Although people take advantages of this new technology and service, their concerns about data security arises as well. Security problem in cloud is the most critical issue because of the valuable information that data owners share. Cloud providers should address privacy and security issues as a matter of high and urgent priority [7–9]. One of the prominent security concerns in data sharing is data privacy. In addition, terminals of users are usually resource-constrained mobile devices with small storage space and low processing speed. Therefore, it is essential to propose an efficient and secure data sharing scheme for mobile devices in cloud computing.
