摘要
针对云存储中的数据安全问题,提出一个四维安全体系。基于机密性、完整性、可控性和可用性,把数据进行四维分类并提供给云端。根据访问数据的类别,用户需要进行不同等级的认证。给出数据存储和访问的架构,方案可以根据不同的应用场景进行扩展。
Focuses on the problem of data security in cloud storage,presents 4 dimensional security architecture. The data is to be categorized on the basis of confidentiality,integrity,controllability and availability.The sensitive data will send for storage to cloud provider.User who wants to access the data need to be authenticated according to the concept of 4D.Gives the structure of data storage and access which can be extended according to different environment.
