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.
