随着云计算技术和服务的不断发展,大规模的云存储已成为一种趋势.在此状况下,如何控制和阻止非授权用户使用云存储中的数据资源已成为一个迫切需要解决的问题.基于这种需求,文章提出一个基于角色加密(RBE)的模式,此模式整合了基于角色的访问控制方法.在基于角色加密模式基础上,文章构建了一个安全RBE-based混合云存储架构.而文章所提出的基于角色加密模式与构建的安全RBE-based混合云存储架构就构成了一种面向数据存储的安全访问控制机制.为了验证这种机制的可行性,文章进行了一系列的实验.实验结果表明,文章所提出的面向数据存储的安全访问控制机制是有效的.

With the rapid development of technology and service of cloud computing, there has been a growing trend to use the cloud for large-scale data storage. This has raised the important security issue of how to control and prevent unauthorized access to data stored in the cloud. Under this state, we ifrst put forward a role-based encryption (RBE) scheme that integrates the cryptographic techniques with the role-based access control (RBAC). Then, we present a RBE-based hybrid cloud storage architecture. All of these constitute a secure access control mechanism for data storage in cloud computing. In order to verify the feasibility of the mechanism, a series of experiments have been done. The experimental results show that it is feasible to ensure the security of access control about data storage in cloud computing.
