Application of data envelope technology in cloud data security

Pei Huihuiqun

Cloud computing in the provision of efficient, flexible service at the same time, there are a variety of security risks. Access control methods can improve the security of cloud data and resources, protect users ' privacy, however, traditional access control methods require large security overhead and result in a large amount of data redundancy. This paper optimizes the strategy through the resource segmentation technology, and constructs a secure data envelope for cloud environment with the help of encryption algorithm and viscous strategy. At the same time, the mapping relationship between resources and data envelopes is established, which enables users to obtain resources that meet the policy requirements by requesting a virtual resource pool. The decision method proposed in this paper changes the traditional traversal rule, realizes the demand decision of the user request, and improves the system security and decision-making efficiency. Finally, through the case of medical privacy, this paper expounds the use environment of the method, and simulates the efficiency of many strategies and rules verification algorithms.
