【摘要】：隨著云存儲(chǔ)技術(shù)的發(fā)展,用戶可以從遠(yuǎn)程云中按需獲取高質(zhì)量的應(yīng)用和服務(wù),而不用擔(dān)心本地的數(shù)據(jù)管理存儲(chǔ).由于用戶在本地不再保留任何數(shù)據(jù)副本,故無法確保云中數(shù)據(jù)的完整性.為了解決這一問題,提出了一種面向于云存儲(chǔ)環(huán)境的、基于格的數(shù)據(jù)完有性驗(yàn)證機(jī)制,該機(jī)制能有效地識(shí)別云存儲(chǔ)中侵犯用戶數(shù)據(jù)完整性的違規(guī)行為,且在隨機(jī)預(yù)言機(jī)模型下被證明是安全的.另外,設(shè)計(jì)的協(xié)議還具有其他3種好的屬性,即支持?jǐn)?shù)據(jù)塊級的動(dòng)態(tài)操作、支持簽名數(shù)據(jù)上的同態(tài)計(jì)算及支持多用戶驗(yàn)證.最后,給出了現(xiàn)有的多種完整性驗(yàn)證機(jī)制之間的對比,以及基于格的數(shù)據(jù)完整性驗(yàn)證方法存在的一些問題及發(fā)展方向.
[Abstract]:With the development of cloud storage technology, users can obtain high-quality applications and services from the remote cloud on demand without worrying about local data management storage. The integrity of the data in the cloud cannot be ensured because the user no longer keeps any copies of the data locally. In order to solve this problem, a lattice-based data completion verification mechanism for cloud storage environment is proposed, which can effectively identify violations of user data integrity in cloud storage. And it is proved to be safe under the model of random prophecy. In addition, the designed protocol has three other good properties, namely, supporting dynamic operation at block level, homomorphic computation on signature data and multi-user verification. Finally, the comparison between the existing integrity verification mechanisms and some problems in the lattice based data integrity verification method and its future development are given.
