Improvement on a Trapdoor Hash Function

By Fuw-yi Yang

Abstract

By appending some bits to the original signature, a trapdoor hash function converts any signature scheme into secure signature scheme with very efficient online computation. Many of them have been proposed. However, all of them require performing a modular reduction during the online phase. The paper presents a trapdoor hash function to get rid of the modular reduction in online computation
