云存储应用中的加密存储及其检索技术

云计算自身的数据安全问题阻碍其推广应用。通过对数据进行加密可以保护企业及个人用户的数据隐私。对加密数据有效检索难以通过传统信息检索方式实现。文章在分析云存储应用中的存储安全技术基础上,针对加密存储的需求,基于常见的加密检索方法和相关技术,结合自己的研究成果,提出了一种基于全同态加密的检索方法,该方法能在一种程度上提高检索效率。

Encrypted Storage and Its Retrieval in Cloud Storage Applications

The problem of data security impedes the spread and application of cloud computing.While corporate and personal data can be protected through data encryption,effective retrieval of encrypted data is difficult to achieve by traditional means.This paper analyzes storage security technology in cloud storage and also the demands of encrypted storage（using common methods of encryption and related technologies）.In light of research results,this paper proposes a retrieval method based on fully homomorphic encryption—which can markedly improve efficiency.
