网络-物理-社会系统（Cyber-Physical-Social System，CPSS）为用户提供安全、高质量的移动的服务应用，实现网络空间和物理世界的数据共享和交换。随着数据的爆炸式增长，有必要在CPSS中引入云存储服务，允许设备频繁地诉诸于云来存储和共享数据。在本文中，我们提出了一个数据存储和共享方案的CPSS的云存储服务的帮助下。由于数据完整性保证是云存储中不可避免的问题，本文首先基于公共审计和双线性映射技术设计了一种安全高效的数据存储方案，同时保证了验证的安全性。为了满足CPSS的实时性和可靠性要求，该方案考虑了及时性激励和有效性激励两方面的奖励。其次，基于所提出的存储方案和ElGamal加密，我们提出了一个轻量级的访问模型，供用户访问云服务器处理的最终数据。我们形式化地证明了该方案的安全性，并进行了性能评估，以验证其高效性。实验结果表明，该方案具有较低的通信和访问开销相比，CDS技术。
Cyber-Physical-Social System (CPSS) provides users secure and high-quality mobile service applications to share and exchange data in the cyberspace and physical world. With the explosive growth of data, it is necessary to introduce cloud storage service, which allows devices frequently resort to the cloud for data storage and sharing, into CPSS. In this paper, we propose a data storage and sharing scheme for CPSS with the help of cloud storage service. Since data integrity assurance is an inevitable problem in cloud storage, we first design a secure and efficient data storage scheme based on the technology of public auditing and bilinear map, which also ensures the security of the verification. In order to meet the real-time and reliability requirements of the CPSS, the rewards of timeliness incentive and effectiveness incentive are considered in the scheme. Secondly, based on the proposed storage scheme and ElGamal encryption, we propose a lightweight access model for users to access the final data processed by cloud server. We formally prove the security of the proposed scheme, and conduct performance evaluation to validate its high efficiency. The experimental results show that the proposed scheme has lower overheads in communication and access as compared to the technique CDS.
