摘要 随着网络技术和云计算的发展,数据共享越来越受欢迎。许多学者对数据共享进行了深入的研究。随着数据共享规模的扩大,数据共享的隐私保护成为研究的热点问题。此外,在数据共享中,很多数据是多方维护的,云共享给保护这些数据的隐私带来了新挑战。在本文中,我们提出了一个使用区块链的可信数据共享方案。我们使用区块链来防止共享数据被篡改,并使用Paillier密码系统实现共享数据的机密性。除了共享数据外,交易信息也是敏感的,我们使用(p,t)-threshold Paillier密码系统来保护它的隐私。并且,我们在云存储场景中进行了实验,实验结果证明了该方案的有效性。

Abstract: With the development of network technology and cloud computing, data sharing is becoming increasingly popular, and many scholars have conducted in-depth research to promote its flourish. As the scale of data sharing expands, its privacy protection has become a hot issue in research. Moreover, in data sharing, the data is usually maintained in multiple parties, which brings new challenges to protect the privacy of these multi-party data. In this paper, we propose a trusted data sharing scheme using blockchain. We use blockchain to prevent the shared data from being tampered with, and use the Paillier cryptosystem to realize the confidentiality of the shared data. In the proposed scheme, the shared data can be traded, and the transaction information is protected by using the (p, t)-threshold Paillier cryptosystem. We conduct experiments in cloud storage scenarios and the experimental results demonstrate the efficiency and effectiveness of the proposed scheme.
