在云计算,数据和服务请求被遥远的进程回答拜访完全没被信任的巨大的数据服务器簇。新计算模式可以引起许多潜在的安全威胁。这份报纸探索怎么与用户钥匙对在云计算保证数据存储的完整和正确性。在这份报纸,我们主要瞄准验证计划由实现云计算费用的平衡策略在数据中心维持数据的快数据块构造,移开顾客的重计算负担,并且使用一个自动数据完整维护方法。在我们的计划,第三方听者(TPA ) 被放在计划,为顾客的缘故,到周期性地检查在数据存储的数据块的完整中心。我们的计划支持快公共的数据完整确认和块冗余性策略。与存在计划相比,它拿海洋数据支持和高效的优点。
In Cloud computing, data and service requests are responded by remote processes calls on huge data server clusters that are not totally trusted. The new computing pattern may cause many potential security threats. This paper explores how to ensure the integrity and correctness of data storage in cloud computing with user's key pair. In this paper, we aim mainly at constructing of a quick data chunk verifying scheme to maintain data in data center by implementing a balance strategy of cloud computing costs, removing the heavy computing load of clients, and applying an automatic data integrity maintenance method. In our scheme, third party auditor (TPA) is kept in the scheme, for the sake of the client, to periodically check the integrity of data blocks stored in data center. Our scheme supports quick public data integrity verification and chunk redundancy strategy. Compared with the existing scheme, it takes the advantage of ocean data support and high performance.
