| Summary: | It is one of important applications of secure multiparty computation that privacy-preserving SQL computation in distributed relational database.There are only few works dealing with provably-secure privacy-preserving data manipulations in contrast with comparatively abundant works on privacy-preserving data-query in database，among which the join operator is the most powerful in generating new data (relation).By making use of anonymous IBE (identity-based encryption) scheme and its user private-keys blind generation techniques，a very general cryptographic protocol framework is proposed for secure 2-party join computation.This construction is provably GUC (generalized universally composable) secure in the standard model with acceptable efficiency. |
