| 摘要: |
| Chameleon签名方案是一种利用Hash-and-Sign模式的非交互签名方案,并且具有不可转移性,只有指定的接收者才可以确信签名的有效性.利用双线性对提出了一种新的Chameleon Hash函数,并在此基础上构建了相应的基于身份的Chameleon签名方案.与传统的Chameleon Hash函数相比,该方案中的Hash函数公钥所有者无须获取相应私钥,除非它企图伪造签名.该方案不但具有通常Chameleon签名方案的所有特点,而且具有基于身份密码系统的诸多优点. |

| Abstract: |
| 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. |
