云计算中数据隐私保护研究进展

由于社会分工和资源共享的必然，公共云平台必将成为和电网、互联网等同等重要的国家基础设施。云计算面临的安全问题制约着云计算的广泛使用。数据安全在云计算中尤为重要，如何保证数据的安全性是云计算安全的核心。从数据的隐私保护计算、数据处理结果的完整性认证、数据访问权限控制以及数据的物理安全4个方面对已有研究工作进行了分类和总结，为后续云计算中数据的安全性研究提供参照。

Survey of privacy preserving data queries in cloud computing

Driven by resource sharing, public clouds will become the national infrastructure like electricity grids and the Internet. A core issue in public cloud computing is privacy. It is crucial for public clouds to provide necessary services while protecting data privacy. Existing work on data privacy from the perspectives of privacy preserving computation was survied, integrity verification of public cloud computing results, public cloud data access control, and hardware security in cloud computing. Existing work is analyzed and future research directions for public cloud privacy is discussed.
