Welcome to the resource topic for 2004/307

Title:
Universal Forgeability of Wang-Wu-Wang Key-Insulated Signature Scheme

Authors: Zhengjun Cao

Abstract:

Wang et al. recently proposed
a new perfect and strong key-insulated signature scheme in [1].
We find that the scheme is universally forgeable. In the
paper we present a simple and direct attack on it.
