An Anonymous Authenticated Protocol Based on Zero Knowledge Proof
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.
