摘要
现有云存储方案无法兼顾冗余存储、数据机密性和存储开销等多方面因素,给诸多用户带来困扰。为克服现有方案的不足,提出一个高效可靠的云存储方案,该方案既能实现数据冗余存储又能保证数据机密性,且不会带来存储空间的剧增。文章给出方案的框架且对方案进行具体的描述,然后从机密性、冗余性和存储开销等方面对方案进行分析,得出本方案可靠性和高效性的优势。
The existing cloud storage schemes can＇t balance redundant storage, data confidentiality and storage costs which troubled many users. In order to overcome the deficiencies of the existing cloud storage scheme, we proposed a reliable cloud storage scheme which suitable for the characteristics of digital library resources. The scheme can realize data redundant storage and can guarantee data confidentiality. In addition, the scheme will not bring a surge in storage space. This paper not only gives a framework of the scheme but also gives a detailed description of the specific scheme. Then, we make an analysis from the confidentiality, redundancy and storage cost etc. of the scheme to improve its reliability and high efficiency.
