New certificateless multiple and unlinkable signature scheme
一个新的无证书多重无链接签名方案*

This paper proposed a new multiple and unlinkable signature scheme based on certificateless public key cryptography.The new scheme allowed the use of a various number of identity-based public keys in different groups or applications while keeping a single signature key.The use of different public keys can guarante public key is unlinkable and the user's privacy can be protected from attackers.The proposed scheme against the adaptive chosen-message attack under the random oracle model.
