云计算存储数据安全访问控制机制研究

Research on Secure Access Control Mechanism of Cloud Computing Storage Data

传统控制机制存在角色分配不合理、加密解密时间耗费长、用户不能安全访问等问题,提出研究一种云计算存储数据安全访问控制机制;根据角色加密原理,构建角色加密混合云存储框架,为了更好访问子系统中各个模块,对用户可信度与行为监控进行分析,以此实现动态监控访问控制机制;通过实验验证可知,该机制能够有效进行角色分配,并对加密、解密和用户访问进行准确控制。

Traditional control mechanisms include irrational role allocation,long time of encryption and decryption,and users can not access safely.According to the role encryption principle,a role encryption hybrid cloud storage framework is built.In order to better access each module in the subsystem,we analyze the user credibility and behavior monitoring,in order to achieve the dynamic monitoring access control mechanism.The experimental verification shows that the mechanism can effectively allocate the role and control the encryption,decryption and user access accurately.
