Abstract:

Chameleon signature schemes are non-interactive signature schemes based on a Hash-and-Sign para-d gm,and are s m lar in efficiency to original signature schemes. However,Chameleon signature schemes Dos-sess non-tranterability,that is to say, only the designated recipient can verify the validitv of a signature.In this papc,an ID-based Chameleon Hash function from the bilinear pairing is proposed, according to which an ID-based Chameleon signature scheme is constructed. As Compared with the conventional Chameleon Hash tunctions,the owner of a public Hash key in the ID-based Chameleon signature scheme does not need to re-trieve the assoc ated secret key.The proposed scheme possesses all the attributes of original Chameleon signa-tures.Moreover,it s of the advantages of the ID-based cryptography based on the bilinear pairing.
