【摘要】：隨著云計(jì)算的飛速發(fā)展,越來(lái)越多的人或者組織開始使用云計(jì)算資源。云計(jì)算的云存儲(chǔ)服務(wù)的一個(gè)最大特點(diǎn)就是其無(wú)限的存儲(chǔ)能力。為了降低管理和成本許多個(gè)人、企業(yè)和組織將他們的數(shù)據(jù)文件外包至云存儲(chǔ)服務(wù)器中。 云存儲(chǔ)服務(wù)方式主要分為兩類：第一類是專用存儲(chǔ),即在云端存儲(chǔ)的數(shù)據(jù)文件有且只有數(shù)據(jù)文件的持有者可以使用；第二類是共享存儲(chǔ),即在云端存儲(chǔ)的數(shù)據(jù)文件可以令多個(gè)共享者使用。本文對(duì)當(dāng)前的云存儲(chǔ)安全現(xiàn)狀進(jìn)行了介紹；并依次按照云存儲(chǔ)中的機(jī)密性、完整性、可用性、監(jiān)控和審計(jì)這5個(gè)安全屬性對(duì)目前云存儲(chǔ)的安全研究狀況作了介紹。介紹了與本文相關(guān)的密碼學(xué)概念；并依此對(duì)加密模型、對(duì)稱加密、公鑰加密、公鑰加密秘密共享技術(shù)和hash函數(shù)進(jìn)行了介紹。 最后,本文以分布式存儲(chǔ)模型為基礎(chǔ),利用AES加密方法對(duì)存儲(chǔ)的數(shù)據(jù)文件進(jìn)行加密,對(duì)已加密數(shù)據(jù)文件進(jìn)行哈希運(yùn)算保證存儲(chǔ)數(shù)據(jù)文件的可驗(yàn)證性；將秘密共享技術(shù)利用到了云存儲(chǔ)方案中,達(dá)到了對(duì)數(shù)據(jù)文件進(jìn)行一次加密而可以令多個(gè)共享者使用,采用子密鑰的影子信息技術(shù)使得子密鑰可多次使用。證明了本方案具有較高的安全性、可以驗(yàn)證服務(wù)器端的惡意篡改,將本文設(shè)計(jì)的云存儲(chǔ)共享方案和已有的存儲(chǔ)共享方案進(jìn)行了比較,結(jié)果表明本文方案具有較低的復(fù)雜度和較高的效率
[Abstract]:With the rapid development of cloud computing, more and more people or organizations begin to use cloud computing resources. Enterprises and organizations outsource their data files to cloud storage servers. Cloud storage services are divided into two main categories: the first is dedicated storage, which has data files stored in the cloud and is available only to the holder of the data file, and the second is shared storage. That is, the data files stored in the cloud can be used by many sharers. This paper introduces the current security situation of cloud storage, and according to the confidentiality, integrity and availability of cloud storage, Monitoring and auditing of these five security attributes of cloud storage security research status is introduced. The related cryptographic concepts are introduced, and the encryption model, symmetric encryption, public key encryption, Public key encryption secret sharing technology and hash function are introduced. Finally, based on the distributed storage model, AES encryption method is used to encrypt the stored data files and hash the encrypted data files to ensure the verifiability of the stored data files. The secret sharing technology is used in the cloud storage scheme, which can encrypt the data file once so that it can be used by more than one user. The shadow information technology of the sub-key makes the sub-key can be used many times. It is proved that this scheme has high security and can verify the malicious tampering on the server side. The cloud storage sharing scheme designed in this paper is compared with the existing storage sharing scheme. The results show that the proposed scheme has lower complexity and higher efficiency.
