GUC-Secure Set-Intersection Computation

TIAN Yuan and WANG Ying

Abstract

Secure set-intersection computation is one of important problems in the field of secure multiparty computation with valuable applications. We propose a very gerneral construction for 2-party set-intersection computation based-on anonymous IBE scheme and its user private-keys blind generation techniques. Compared with recently-proposed protocols, e.g., those of Freedman-Nissim-Pinkas, Kissner-Song and Hazay-Lindell, this construction is provabley GUC-secure in standard model with acceptable efficiency. For this goal a new notion of non-malleable zero-knowledge proofs of knowledge and its efficient general construction is presented. In addition, we present an efficient instantiation of this general construction via anonymous Boyen-Waters IBE scheme.
