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.

针对云计算中的移动设备的高效且安全的数据共享方案

随着大数据和云计算的发展，越来越多的企业希望将数据存储在云中，并在授权的员工之间高效安全地共享数据。迄今为止，已经提出了不同领域中的许多不同的数据共享方案。但是，在云中共享敏感数据仍然面临一些挑战，例如在资源受限的移动终端上实现数据隐私和轻量级操作。此外，大多数数据共享方案没有完整性验证机制，这将导致用户错误的计算结果。为了解决这些问题，我们为云计算中的移动设备提出了一种高效且安全的数据共享方案。首先，该方案可确保共享敏感数据的安全性和授权访问。其次，该方案在用户共享数据之前实现了有效的完整性验证，避免了错误的计算。最后，该方案实现了数据所有者和数据请求者双方的移动终端的轻量级操作。
