基于云计算的安全存储隐私保护数据协议

Privacy Preserving Data Protocol for Secure Storage Based on Cloud Computing

移动云计算(MCC)有效减轻移动终端数据存储产生的开销,但不能控制外包数据的完整性。为此,提出基于云计算的安全存储隐私数据保护协议(T-PDP),引入可信的第三方审计员(TPA)验证云存储数据的正确性,在此过程中不需检索整个数据库。验证表明,所提出的方法有效节省了移动终端的计算资源,减少审计开销,从而提高云存储服务的成本效益。

Mobile Cloud Computing(MCC)can effectively reduce the cost of data storage in mobile terminals,but it can not control the integrity of outsourced data.Therefore,a secure storage privacy data protection protocol(T-PDP)based on cloud computing is proposed.Trusted third-party auditors(TPA)are introduced to verify the correctness of cloud storage data,and the whole database is not needed to be retrieved in the process.The validation shows that the proposed method can effectively save the computing resources of mobile terminals,reduce audit overhead,and improve the cost-effectiveness of cloud storage services.
