Key exposure free chameleon hash schemes based on discrete logarithm problem

Abstract

A chameleon hash scheme is a trapdoor collision-resistant hash scheme, and it provides many interesting features in signature schemes with hash-and-sign construction. In this paper, we introduce the notion of key exposure threshold t for a chameleon hash scheme for which a key exposure free chameleon hash scheme can be understood as the case with t=1. We… (More)
