摘要
针对当前流行的云服务器环境,提出基于隐私保护的PFKS算法;在传统的DFSC算法和OPM密文检索算法基础之上,增加多关键字检索、模糊检索以及排序检索,且改进索引结构.研究结果表明该算法在云服务器环境下的安全性上,在算法的精度上,特别是一对多保序映射算法的正确性上,具有较大的提升.
A privacy protection based PFKS algorithm is proposed for the popular cloud server environment.Based on the traditional DFSC algorithm and OPM ciphertext retrieval algorithm,multi-keyword retrieval,fuzzy retrieval and sorting retrieval are added,and the index structure is improved.The research results show that the algorithm is safe in the cloud server environment,and the accuracy of the algorithm,especially the correctness of the one-to-many preserving mapping algorithm,is greatly improved.
