摘要:With the rapid development of the Internet, anonymity and privacy protection in many applications of the scene is critical. The anonymous authentication means that the server cant know the users identity when they are communicating with each other. In this paper, based on the Wangs zero knowledge proof scheme of possessing a digital signature, we propose a new anonymous authentication scheme. Compared with the Cui-Caos anonymous authentication protocol based on the ring signature, our scheme has two advantages. First, we dont need to know all users public keys. And then our scheme reduces the communication traffic largely. We also discuss the security attributes of our new scheme which are authentication, anonymity and unlinkablity. And then we introduce a concrete application of our scheme. Finally, we make a conclusion of this paper.
