高效可扩展的对称密文检索架构
Efficient and scalable architecture for searchable symmetric encryption
摘要
Abstract
The existing encryption schemes were usually poor of index construction and maintenance,which was difficult to meet the retrieval requirements for distributed ciphertext.Aiming at the above shortage of existing schemes,a structure of separable ciphertext inverted index was proposed for improving the performance of parallel constructing cryptograph index,simplifying the data maintenance process,and increasing the compatibility with the traditional NoSQL system.The method of centralized inverted index was adopted to improve the retrieval efficiency of distributed retrieval system.Then,the proposed scheme was proved to meet the widely adopted IND-CKA security standard.Finally,Cassandra was combined to evaluate the several performance parameters,and the experimental results show proposed architecture has good applicability to the distributed and massive encrypted data environment.关键词
