摘要
为了解决云存储技术带来的数据安全和高效检索问题,在深入研究可搜索加密技术基础上,提出一种基于云存储的密文全文检索模型,给出基于可搜索加密技术的密文全文索引构建和检索策略,并对方案的安全性进行分析。实验表明,云存储环境下基于可搜索加密技术的密文全文检索方案既保证了数据的安全性,又具有很好的检索效率,可适用于海量数据的加密存储与高效安全检索。
To solve the problems of data security and efficient retrieval in cloud storage technology, on the basis of in-depth study searchable encryption, a ciphertext full-text retrieval model based on cloud storage is proposed. We give the ciphertext full-text index building and search strategies based on searchable encryption and analyze the security of the scheme. Experimental results show that the ciphertext full-text retrieval scheme based on searchable encryption in cloud environment not only ensures the security of data, but also has good retrieval efficiency, so it can be applied to the mass storage of data encryption and efficient security search.
