Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm,and similar in efficiency to regular signatures.The distinguishing characteristic of chameleon signatures is that they are non-transferable,with only the designated recipient capable of asserting its validity.This paper introduces a new chameleon hash function based on bilinear pairing and builds the ID-based chameleon signature scheme.Compared with the conventional chameleon hashing functions,the owner of a public hash key in the ID-based chameleon hashing scheme does not necessarily need to retrieve the associated secret key.The scheme enjoys all the attributes in the normal chameleon signature and the added characteristics of ID-based cryptography based on bilinear pairing.
