Privacy Preserving Query Processing on Secret Share Based Data Storage

摘要: Database as a Service(DaaS) is paradigm for data management in which the Service Provider(DSP), usually professional third party management, can host database service. Many security and query problems are brought about because of possible untrusted or malicious DSP this context. Most proposed papers concentrated on using symmetric encryption to guarantee confidentiality delegated data, partition based index help execute privacy preserving range query. However, decryption operations large volume time consuming, results always consist many irrelevant tuples. Different from scheme, paper, we present secret share scheme data. And what more important, construct accelerate return exactly required Finally analyze properties demonstrate efficiency response our approach through empirical
