ID-based Chameleon Digital Signature Scheme

Chameleon signature is a non-interactive signatures,and its building block is Chameleon Hash function,a trapdoor one-way Hash function.The distinguishing characteristic of Chameleon signature is non-transferable and non-repudiation.This paper proposes a ID-based Chameleon digital signature which makes use of ID-based signature scheme from bilinear pairings byte Combining with Chameleon Hash function.Compared with the conventional Chameleon Hash functions,the owner of a public Hash key in the ID-based Chameleon Hash scheme does not necessarily need to retrieve the associated secret key in the scheme and it is an appointed verifier scheme.
