摘　　要：定义并构造了模n下的整体同态加密系统,利用该类系统的整体同态性构造了基于身份的多重变色龙散列函数,并给出了该函数的应用——基于身份的多重变色龙签名,它不仅具有普通变色龙签名的特点,而且签名结果对于所有指定接收人中任意一个人都具有不可传递性,省去了公钥证书管理的代价,且伪造签名并不会引发所有指定接收人中任何个人密钥的泄露.The holistic homomorphic encryption system under modular n is defined and constructed. By u- sing the holistic homomorphism property of this system, the ID-based multi-chameleon hash function is constructed and its application,ID-based mult-chameleon signature, is presented, which not only has the properties of the ordinary chameleon signature but also has the following properties：The signature is nontransferable for anyone of the designated receivers; it has not the cost for public key managements; the forgery of the ID-based muh-chameleon signature does not disclose the secret key of anyone of the designated receivers.

关 键 词：数字签名 变色龙散列函数 公钥
