面向云存储的访问控制系统的研究

摘要

For the purpose of secure cloud storage ,a secure cloud storage access control system scheme is proposed in this paper .In the scheme ,Linux and Hadoop are used to build the cloud platform .T he role-based access control method is employed to test identity and to access nonsensitive data . And the attribute encryption algorithm is applyed to encrypt/decrypt data .Experiment show s that this scheme can effectively ensure the integrity and confidentiality of data in the cloud storage .%为了达到安全云存储的目的，提出一种安全云存储的访问控制系统方案，该方案在Linux下使用Hadoop搭建云平台，并利用基于角色的访问控制方法进行用户身份的验证和非敏感数据的访问，采用属性加密算法对数据进行加解密操作。实验证明此方案能够有效保障云存储中数据的完整性和保密性。
