Comments and Improvements on Chameleon Hashing Without Key Exposure Based on Factoring
Abstract
In this paper, we present some security flaws of the key-exposure free chameleon hash scheme based on factoring \cite{GWX07}. Besides, we propose an improved chameleon hash scheme without key exposure based on factoring which enjoys all the desired security notions of chameleon hashing.
