【摘要】：隨著云計算技術(shù)的不斷發(fā)展,云存儲目前也成為了計算機(jī)領(lǐng)域的研究熱點(diǎn),其相關(guān)技術(shù)是解決海量數(shù)據(jù)存儲問題的有效方案。研究如何提高云存儲系統(tǒng)的機(jī)密性和可用性,對于保障云存儲過程中的數(shù)據(jù)安全、進(jìn)一步促進(jìn)云存儲技術(shù)發(fā)展具有重大意義。然而現(xiàn)存的主流云存儲系統(tǒng),在安全保障機(jī)制方面,尤其是在保證數(shù)據(jù)的機(jī)密性和可用性方面手段單一。 本文針對上述不足,對高機(jī)密性高可用性的云存儲系統(tǒng)展開了研究,主要貢獻(xiàn)包括： ◆提出了采用數(shù)據(jù)拆分和重建算法以及數(shù)據(jù)冗余策略提高數(shù)據(jù)的機(jī)密性和可用性； ◆結(jié)合數(shù)據(jù)拆分和重建算法以及開源HDFS (Hadoop分布式文件系統(tǒng))設(shè)計了新的數(shù)據(jù)塊控制流程,實現(xiàn)了HCAFS(高機(jī)密性和可用性文件系統(tǒng))云存儲原型系統(tǒng)； ◆對HDFS和HCAFS進(jìn)行了大量的性能對比測試,給出了測試結(jié)果及分析； ◆為了更好的監(jiān)控文件系統(tǒng)的表現(xiàn),設(shè)計和實現(xiàn)了云服務(wù)監(jiān)控與管理平臺。
[Abstract]:With the continuous development of cloud computing technology, cloud storage has also become a hot topic in the field of computer research. Its related technology is an effective solution to the problem of massive data storage. It studies how to improve the confidentiality and availability of the cloud storage system, and further promote the development of cloud storage technology to further promote the development of cloud storage technology. It is of great significance. However, the existing mainstream cloud storage systems have a single way of ensuring the confidentiality and availability of data, especially in terms of security mechanisms.
In view of the above shortcomings, the cloud storage system with high confidentiality and high availability has been studied. The main contributions include:
The data splitting and reconstruction algorithm and data redundancy strategy are proposed to improve the confidentiality and availability of data.
The new data block control process is designed based on the data splitting and reconstruction algorithm and the open source HDFS (Hadoop distributed file system), and the HCAFS (high confidentiality and availability file system) cloud storage prototype system is realized.
A large number of performance comparison tests between HDFS and HCAFS are carried out, and the test results and analysis are given.
In order to better monitor the performance of the file system, a cloud service monitoring and management platform is designed and implemented.
