Structure-preserving signatures (SPS) are pairing-based signatures
where all the messages, signatures and public keys are group elements, with
numerous applications in public-key cryptography. We present new,
simple and improved SPS constructions under standard assumptions via a
conceptually different approach. Our constructions significantly
narrow the gap between existing constructions from standard assumptions
and optimal schemes in the generic group model.
