随着云计算技术的应用及发展,作为其基础组成部分的云存储及其安全性问题成为目前研究的重点.然而,现阶段技术条件下,云存储依然存在数据安全性和保密性等安全问题,这是云存储发展的所必须解决的问题.针对云存储中数据共享及保密性问题,提出了一个基于属性的匿名云存储策略RACSS.建立云访问控制模型,采用对称非对称加密算法加密数据明文,使用CP_ABE算法建立访问控制体系,实现多用户数据共享,并结合二叉树前缀编码及匿名乱序存储方法存储数据,在不可信的云存储环境下,保证数据的安全存储.最后对RACSS进行了安全性分析和比较分析.
With the application and development of cloud computing technology, cloud storage and its security as its basic components become the focus of current research.However, under the current technical conditions, cloud storage still has security issues such as data security and confidentiality , Which is a problem that must be solved in the development of cloud storage.Aiming at the problem of data sharing and confidentiality in cloud storage, an attribute-based anonymous cloud storage strategy named RACSS is proposed.A model of cloud access control is established, using symmetric asymmetric encryption algorithm to encrypt data Plaintext, using CP_ABE algorithm to establish access control system, to achieve multi-user data sharing, combined with binary tree prefix encoding and anonymous out of order storage method to store data in an untrusted cloud storage environment, to ensure data security.Finally, the RACSS Security Analysis and Comparative Analysis.
