云计算中数据隐私的安全保护机制

在云计算中,用户所拥有的数据信息通常被存放在遥远的云端,而其它用户常常能够访问这些数据且这些数据通常不由数据拥有者自己控制和管理.在此状况下,如何在云计算中保护用户的数据隐私安全则是一个十分具有挑战性的问题.为了解决这个问题,本文提出了一种数据隐私的安全保护机制.在此安全保护机制中,针对用户数据上载和访问的过程,首先提出了一种数据隐私保护的安全流程.在此基础上,提出了用户数据安全存储算法和云端数据安全访问算法.为了证明这种保护机制的有效性,本文对其安全性能进行了一系列的分析.分析结果表明：在云计算中使用这种机制能够确保数据隐私的安全性.

A Secure Protection Mechanism for Data Privacy in Cloud Computing

In cloud computing, data owner stores their data to remote servers and users also access required data from cloud servers which is not controlled and managed by data owners.In this situation, it becomes a challenge problem that how to protect the security of data privacy of users in cloud computing.In order to solve this problem, we propose a secure protect mechanism for data privacy in cloud computing.In the protection mechanism, considering the processes that users upload data to cloud servers and access required data from cloud servers, we first put forward a secure process of data in order to protect the security of data privacy.Based on the secure process of data, we put forward two algorithms.One is the secure storage algorithm of data and another is the secure access algorithm of data.In order to justify the feasibility of the protection mechanism, the safety performance of the protect mechanism is analyzed.The results show the mechanism can ensure the security of data privacy in cloud computing.
