發(fā)布時間:2018-08-13 11:49
【摘要】:云計算最早由Google提出,是融合了網(wǎng)格計算、分布式計算、并行計算、效用計算、虛擬化等傳統(tǒng)計算機和網(wǎng)絡技術的一種新的計算模式。云計算不僅僅實現(xiàn)了IT技術的革新,更是IT商業(yè)模式和服務模式的一次重大革命。隨著云計算技術應用的進一步深入,云安全也成為IT界關注的焦點。如何保證“云”中數(shù)據(jù)的安全,是云計算面臨的關鍵問題。 本文主要研究云計算的安全問題,重點研究了其中數(shù)據(jù)安全的關鍵性問題和相關的技術解決方案。 首先,本文詳細介紹了云計算的發(fā)展、特征、體系架構及應用現(xiàn)狀,,分析了云計算存在的安全風險和問題,總結了相應的安全策略,并在此基礎上提出了一個基于云計算層次結構的安全框架。 其次,研究了云計算數(shù)據(jù)安全的問題。從云數(shù)據(jù)的生命周期出發(fā),分析了各階段數(shù)據(jù)安全的需求,總結了數(shù)據(jù)安全的隱患與風險;介紹了大型分布式數(shù)據(jù)系統(tǒng)BigTable,探討了確保云計算數(shù)據(jù)機密性和完整性的安全策略;重點研究了云數(shù)據(jù)安全的密鑰管理策略、數(shù)據(jù)加密技術、云計算的身份認證和訪問管理(IAM)方案。 最后,本文研究了全同態(tài)加密算法的特性,在此基礎上提出了一個基于全同態(tài)加密算法的云數(shù)據(jù)安全方案,并對該方案的應用場景進行了分析。
[Abstract]:Cloud computing was first proposed by Google as a new computing model that combines grid computing, distributed computing, parallel computing, utility computing, virtualization and other traditional computer and network technologies. Further in-depth, cloud security has become the focus of the IT community. How to ensure the security of data in the "cloud" is the key issue facing cloud computing.
This paper mainly studies the security of cloud computing, focusing on the key issues of data security and related technical solutions.
Firstly, this paper introduces the development, characteristics, architecture and application status of cloud computing in detail, analyzes the security risks and problems of cloud computing, summarizes the corresponding security strategies, and proposes a security framework based on cloud computing hierarchy.
Secondly, the problem of data security in cloud computing is studied. Starting from the life cycle of cloud data, the requirements of data security in different stages are analyzed, and the hidden dangers and risks of data security are summarized. According to the security key management strategy, data encryption technology, cloud computing authentication and access management (IAM) scheme.
Finally, this paper studies the characteristics of homomorphic encryption algorithm, and proposes a cloud data security scheme based on homomorphic encryption algorithm, and analyzes the application scenario of this scheme.
