Welcome to the resource topic for 2009/204

Title:
GUC-Secure Join Operator in Distributed Relational Database

Authors: TIAN Yuan

Abstract:

Secure Join-operator computation in distributed relational databases is one of important problems in the field of secure multiparty computation with valuable applications. We propose a gerneral construction for 2-party Join computation based-on anonymous IBE scheme and its user private-keys blind generation techniques. The construction is GUC(Generalized Universally Composable) secure in standard model. For this goal a new notion of non-malleable zero-knowledge proofs of knowledge and its efficient general construction is also presented.
