Efficiency improvements for signature schemes with tight security reductions
Abstract
Much recent work has focused on constructing efficient digital signature schemes whose security is tightly related to the hardness of some underlying cryptographic assumption. With this motivation in mind, we show here two approaches which improve both the computational efficiency and signature length of some recently-proposed schemes: Diffie-Hellman signatures. Goh and Jarecki [18] recently analyzed a signature scheme which has a tight security reduction to the computational Diffie-Hellman problem. Unfortunately, their scheme is less efficient in both computation and bandwidth than previous schemes relying on the (related) discrete logarithm assumption. We present a modification of their scheme in which signing is 33% more efficient and signatures are 75% shorter; the security of this scheme is tightly related to the decisional Diffie-Hellman problem. PSS. The...

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
