Secure set-intersection computation is one of the important problems in secure multiparty computation. We propose a general protocol construction for secure 2-party set-intersection computation based-on the anonymous IBE scheme and its user private-keys blind generation techniques. Compared with related works, this construction is provably GUC (generalized universally composable) secure in standard model with acceptable efficiency. In addition, an efficient instantiation based-on the Boyen-Waters IBE scheme is also presented.
