【摘要】：数据安全问题是云存储系统中需要解决的关键问题之一,为保证云存储服务器中数据的完整性,数据的持有性证明就显得尤为重要.数据的持有性证明就是用户实时知道其数据是否仍然完整、有效、正确地保存在云存储系统中,以及是否可以随时、随地获取到该数据,这是云存储安全中的挑战性问题.DNA(Deoxyribonucleic Acid)是生物遗传信息,每个DNA都是由若干个RNA(Ribonucleic Acid)组成,研究基于第三方审计(third-party audits,TPA)数据持有性证明模型的基础上,利用这一生物学原理提出了一个高效的数据可持有性证明方案.实验结果表明,该方案在存储性能和计算性能方面与S-PDP方案相比,需额外存储开销较小,约为文件大小的1.17%;而计算开销比S-PDP和CS-PDP方案都小,特别是比S-PDP方案要小很多.
[Abstract]:Data security is one of the key problems to be solved in cloud storage system, in order to ensure the integrity of data in cloud storage server. Data holding proof is particularly important. Data holding proof is that users know whether their data is still complete, effective, correctly stored in cloud storage system, and whether it can be kept at any time. Access to this data anywhere is a challenging issue in cloud storage security. DNA deoxyribonucleic Acidis is biogenetic information. Each DNA is composed of several RNA(Ribonucleic incidences, and the study is based on third-party audit third-party audits. On the basis of TPA data holding proof model, an efficient scheme of data holding proof is proposed based on this biological principle. The experimental results show that the proposed method is effective. Compared with S-PDP scheme, the storage performance and computing performance of this scheme need less extra storage cost, which is about 1.17% of the file size. The computational cost is much less than that of S-PDP and CS-PDP, especially the S-PDP.

【正文快照】： 面对计算资源不足、任务繁琐、数据量庞大、密钥管理等问题的不断迸发,云租户-服务器模式的数据持有性证明已经不能满足用户的需求.因而一些专家学者们把目光转向了能够满足用户需求的第三方审计(third-party audits,TPA),由可信的第三方代替用户检验数据是否真实完整地存在,，
