An Anonymous Authenticated Protocol Based on Zero Knowledge Proof
Chao Jing · 2012
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 can’t know the user’s identity when they are communicating with each other. In this paper, based on the Wang’s zero knowledge proof scheme of possessing a digital signature, we propose a new anonymous authentication scheme. Compared with the Cui-Cao’s anonymous authentication protocol based on the ring signature, our scheme has two advantages. First, we don’t 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.
