Sensitive Information Retrieval Method with Minimal Information Sharing
Ying Li · Jisuanji gongcheng · 2009
Sensitive Information Retrieval(SIR) is a hotspot in research of secure multi-party computation.But the existing methods of SIR method can not protect user's information very well during query.This paper introduces the oblivious third party,indistinguishable concept and the assumption of combination commutative encryption in semi-honest model.A SIR method based on sharing of least information is proposed,which can apply to documentary data retrieval efficiently.Analysis and proof on security and correctness of the method are presented.
