The Zero-Knowledge Proof Technique: Limitations and Challenges

Zero-knowledge proof is one of the techniques implemented in a variety of data security applications. ZKP is a security procedure between two parties, one as the prover and the other as the verifier. The prover and the verifier exchange information without allowing any kind of sensitive information to leak. In this paper, we mention the challenges and limitations that face the zero-knowledge technique when utilized in authentication and privacy protection processes in different environments. We help to produce improvements to the most common zero-knowledge protocol to show many factors that would have greatly contributed to the success of the authentication process.
