摘要
云计算技术为数据存储与计算提供了一个非常有效的方法,当前研究工作的重点集中在云中的数据安全。基于混合云,提出一个安全数据存储架构,将数据存储过程划分为两部分。数据的机密性、完整性和可追踪性的相关操作在私有云中实现,公共云实现数据的存储与查询。该架构在保障云端数据安全存储的同时,降低企业在保证云数据安全存储方面的成本。
Cloud computing promises a more cost effective enabling technology to data storage and com- putations. Data security is one of the most challenging research work in cloud computing. Based on mixed cloud, presents an architecture of secure data storage. The process of data storage is divided into two parts. Realizes confidentiality, integrity and traceability in private cloud, while data storage and search in public cloud. This architecture can assure data storage secure and low enterprise cost in cloud computing simultaneously.
