移动云服务环境中办公资源的安全访问控制技术研究（英文）

Research on secure access control of office resources in mobile cloud service environment

由于云计算环境中无线办公网络环境的复杂性,导致移动端用户的数据资源存在较大的安全性隐患,因此为了提高移动云服务环境中办公数据访问的安全性,提出了一种基于改进CP-ABE(ciphertext-policy attributed-based encryption)的安全访问控制机制。该方法通过结合电子签章技术,对传统属性加密方案进行了改进,实现了更加高效的移动云计算安全访问控制。仿真实验结果显示:相比其他方法,提出方法所需计算开销和存储更小,且运算效率更高,适用于云服务环境中移动端用户的多种办公应用。

Due to the complexity of the wireless office network environment in the cloud computing environment,the data resources of the mobile terminal users have a big security risk.In order to improve the security of office data access in mobile cloud service environment,a secure access control mechanism based on improved CP-ABE（ciphertext-policy attributed-based encryption） is proposed in this paper.By combining the electronic signature technology,the proposed method improves the traditional property encryption scheme and achieves a more efficient mobile cloud computing security access control.Simulation results show that the proposed method requires less computational overhead and less storage as compared with other methods and has more computational efficiency.Therefore,it is suitable for a variety of office applications for mobile users in a cloud service environment.
