【摘要】：近年來(lái),云計(jì)算成為一個(gè)備受關(guān)注的新技術(shù)。云計(jì)算是指通過(guò)“網(wǎng)絡(luò)+互聯(lián)網(wǎng)”的組合模式向用戶提供按需支付的一種計(jì)算模式,使軟件、硬件資源作為像水和電一樣的公共服務(wù)方便、快捷地提供給用戶。云存儲(chǔ)是云計(jì)算的一個(gè)延伸概念,即將個(gè)人電腦、手機(jī)或其他存儲(chǔ)設(shè)備的存儲(chǔ)任務(wù)交由服務(wù)器完成,釋放本身的存儲(chǔ)空間。 數(shù)據(jù)存儲(chǔ)到云存儲(chǔ)服務(wù)器時(shí),其安全性、健壯性、隱私性等問(wèn)題則成為一系列非常重要且敏感的問(wèn)題。本文旨在研究云存儲(chǔ)過(guò)程中的這些問(wèn)題,主要貢獻(xiàn)有： 1.首先,提出了一種便于對(duì)數(shù)據(jù)進(jìn)行監(jiān)控與管理的應(yīng)用于私有云環(huán)境下的安全分布式云存儲(chǔ)模型。該模型中,利用分布式糾刪碼技術(shù),密文數(shù)據(jù)被分塊編碼處理后存儲(chǔ)在若干個(gè)云存儲(chǔ)服務(wù)器中,提高了模型的健壯性。應(yīng)用了多屬性服務(wù)器模式對(duì)屬性進(jìn)行分管及對(duì)應(yīng)屬性私鑰的分布式分發(fā),模型中存在一個(gè)中心授權(quán)服務(wù)器,便于對(duì)數(shù)據(jù)進(jìn)行監(jiān)控和管理。 2.其次,提出了一種應(yīng)用于混合云環(huán)境下的完全分布式云存儲(chǔ)模型。在基于屬性加密技術(shù)基礎(chǔ)上,去除絕對(duì)的可信中心的干預(yù),所有服務(wù)器完全獨(dú)立式工作。整個(gè)屬性私鑰分發(fā)過(guò)程遵循完全的分布式特點(diǎn),無(wú)任何可信中心的存在,改善了模型的安全性,也更適用于混合云環(huán)境中。 3.最后,研究了兼顧數(shù)據(jù)內(nèi)容、身份信息、訪問(wèn)結(jié)構(gòu)三項(xiàng)隱私保護(hù)的模型實(shí)現(xiàn)。在保證數(shù)據(jù)安全性的基礎(chǔ)上,提出了保護(hù)加解密者身份信息和訪問(wèn)結(jié)構(gòu)中的屬性信息的模型。該模型實(shí)現(xiàn)云存儲(chǔ)的安全性、健壯性及隱私保護(hù)的功能。
[Abstract]:In recent years, cloud computing has become a concerned new technology. Cloud computing is a kind of computing mode that provides users with on-demand payment through the combination mode of "network Internet", which makes software and hardware resources as public services such as water and electricity to be provided to users conveniently and quickly. Cloud storage is an extended concept of cloud computing, in which the storage tasks of personal computers, mobile phones or other storage devices are left to the server to free up its own storage space. When data is stored in cloud storage server, its security, robustness and privacy become a series of very important and sensitive issues. The purpose of this paper is to study these problems in cloud storage. The main contributions are as follows: 1. Firstly, a secure distributed cloud storage model is proposed, which is easy to monitor and manage data in private cloud environment. In this model, using distributed erasure code technology, ciphertext data is processed in blocks and stored in several cloud storage servers, which improves the robustness of the model. The multi-attribute server mode is applied to manage the attributes and distribute the private keys of the corresponding attributes. There is a central authorization server in the model, which is convenient to monitor and manage the data. 2. Secondly, a fully distributed cloud storage model for mixed cloud environments is proposed. On the basis of attribute-based encryption, all servers work independently without the intervention of absolute trusted center. The whole attribute private key distribution process follows the completely distributed characteristic, without any trusted center, which improves the security of the model and is more suitable for the mixed cloud environment. 3. Finally, the implementation of three privacy protection models, including data content, identity information and access structure, is studied. On the basis of ensuring data security, a model for protecting encryptor identity information and attribute information in access structure is proposed. The model realizes the security, robustness and privacy protection of cloud storage.
