Title:
ID-Based Chameleon Hashes from Bilinear Pairings
Authors: Fangguo Zhang, Reihaneh Safavi-Naini, Willy Susilo
Abstract:Chameleon hash function is a trapdoor one-way hash function. The
ID-based chameleon hash function was first introduced by Ateniese
and Medeiros \cite{AM03}. As discussed by \cite{AM03}, the general
advantages of ID-based cryptography over conventional cryptography
with respect to key distribution are even more pronounced in a
chameleon hashing scheme, because the owner of a public key does
not necessarily need to retrieve the associated secret key. In
this paper, we propose two new ID-based Chameleon hashing schemes
from bilinear pairings. Also we analyze their security and
efficiency. Based on these ID-based chameleon hashes, ID-based
chameleon signature schemes can be designed.
