We demonstrate that this representation technique can be applied retroactively by any device (rather than only by the signer), thereby facilitating transitioning to always generating ECDSA signatures in this way, without changing standardized ECDSA specifications with instantiations with prime- order curves. This facilitates verifying devices to reap the significant speed-up potential (ranging from \textasciitilde{}1.3x to \textasciitilde{}6x) fast verification techniques afford.}, }
