【摘要】：隨著云存儲技術(shù)的發(fā)展,用戶可以從遠程云中按需獲取高質(zhì)量的應用和服務,而不用擔心本地的數(shù)據(jù)管理存儲.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環(huán)境的、基于格的數(shù)據(jù)完有性驗證機制,該機制能有效地識別云存儲中侵犯用戶數(shù)據(jù)完整性的違規(guī)行為,且在隨機預言機模型下被證明是安全的.另外,設計的協(xié)議還具有其他3種好的屬性,即支持數(shù)據(jù)塊級的動態(tài)操作、支持簽名數(shù)據(jù)上的同態(tài)計算及支持多用戶驗證.最后,給出了現(xiàn)有的多種完整性驗證機制之間的對比,以及基于格的數(shù)據(jù)完整性驗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.
