摘要/Abstract

摘要： Chameleon签名方案是一种基于Hash—and—Sign模式的非交互签名方案，就效率而言该方案和普通的签名方案类似．Chameleon签名方案具有非转移性，也就是只有指定的接收方才可以验证签名的有效性．文中提出了一种基于双线性对和身份的Chameleon Hash函数，并以此构建了一个基于身份的Chameleon签名方案．和传统的Chameleon Hash方案相比，基于身份的Chameleon签名方案中公开Hash密钥的所有者无需恢复相应的私钥．该方案具有普通Chameleon签名方案的所有特点，同时还具有利用双线性对构建的基于身份的密码系统的诸多优点.

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.
