摘　　要：云存储技术的发展,不仅提供了超大容量的数据存储空间,而且可以实现数据共享,逐渐成为企业用户和个人用户存储重要数据的一种主流选择。但是云端数据也面临着信息安全风险,如何防止数据丢失和隐私泄露,成为云服务供应商考虑的关键问题。提出一种基于区块链的数据隐私及数据共享保护技术,在分析隐私保护实现原理、系统模型组成的基础上,对其保护性能展开了评估。结果表明,使用NTRU密码系统可以实现数据的快速加密解密,并且加密方案具有认证性和不可伪造型,可保证数据在存储与共享状态下的安全性。The development of cloud storage technology not only provides large-capacity data storage space, but also enables data sharing, and has gradually become a mainstream choice for enterprise users and individual users to store important data. However, cloud data also faces information security risks. How to prevent data loss and privacy leakage has become a key issue for cloud service providers. This paper proposes a data privacy and data sharing protection technology based on blockchain, and evaluates its protection performance on the basis of analyzing the realization principle of privacy protection and the composition of the system model. The results show that the use of NTRU cryptosystem can realize fast encryption and decryption of data, and the encryption scheme is authenticated and unforgeable, which can ensure the security of data in the state of storage and sharing.
