For the unsuitabihty of the Tag-KEM/DEM to be used as multi-message hybrid encryptions, a new hybrid paradigm, KEM/Tag-DEM, is proposed with its security proof. For the corresponding multi-message hybrid paradigm, KEM/Tag-SKE, security is also proved. Two constructions for IND-CCA secure Tag-DEMs are proposed with the security proof.
