保护隐私的轻量级云数据共享方案

针对基于隐私保护的云数据共享系统中用户需要持有大量密钥、密钥管理困难的问题,提出了一种轻量级的云数据共享方案。在介绍基于公有云的数据共享系统架构的基础上,描述了基于广播加密、可搜索加密等密码学技术构建的数据共享方案,并讨论了数据共享系统的工作流程。与传统的云数据共享系统相比,所提出的方案无须可信的私有云,可以降低客户的投资,而且用户无须随身携带所有密钥,增加了系统的灵活性。...

Aiming at resolving the problem that massive keys existing in the user side in most of privacy-preserving data sharing systems based on the cloud storage, this paper proposed a lightweight data sharing scheme. It introduced the data sharing system architecture based on public cloud, described the data sharing scheme in details and further discussed the work flows in the real data sharing system built by the proposed scheme. Compared with traditional data sharing systems, this scheme doesn＇ t need trusted private cloud and thus r
