Universally Composable Key-evolving Signature

Jin Zhou, TingMao Chang, YaJuan Zhang, and YueFei Zhu

Abstract

The standard digital signature scheme can be easily subject to key exposure problem In order to overcome this problem; a feasible and effective approach is employed by key-evolving signature scheme. In this paper, we study key- evolving signature within the UC framework and propose an appropriate ideal functionality that captures the basic security requirements of key-evolving signature. Then, we present a generic way to transform a key-evolving signature scheme into a real-life protocol. Finally, we show that UC definition of security is equivalent to previous definition of security which is termed as EU-CMA security.
