Chameleon hash function是一个单向hash函数。基于ID的变色龙哈希函数最早由Ateniese和Medeiros [1]提出。如[1]所讨论的，基于ID的密码术相对于传统密码术在密钥分发方面的一般优势在变色龙散列方案中甚至更加明显，因为公钥的所有者不一定需要检索相关联的秘密密钥。在本文中，我们提出了两个新的基于身份的变色龙哈希方案的双线性对。并分析了它们的安全性和效率。基于这些基于身份的变色龙散列，可以设计基于身份的变色龙签名方案。
Chameleon hash function is a trapdoor one-way hash function. The ID-based chameleon hash function was first introduced by Ateniese and Medeiros [1]. As discussed by [1], the general advantages of IDbased cryptography over conventional cryptography with respect to key distribution are even more pronounced in a chameleon hashing scheme, because the owner of a public key does not necessarily need to retrieve the associated secret key. In this paper, we propose two new ID-based Chameleon hashing schemes from bilinear pairings. Also we analyze their security and efficiency. Based on these ID-based chameleon hashes, IDbased chameleon signature schemes can be designed.
