Removing the Outliers of Diverse Zero-Knowledge Proof Systems using Mahalanobis Distance

Abstract

The purpose behind zero-knowledge proofs are to deliver a mystification to the verifier, so that the verifier will not comprehend the information sent by the prover. Cryptography and complexity theory have gained a lot of importance because of zero-knowledge proofs. An enigmatic outset was dignified, that lead to the foundation zero-knowledge proof systems. Zero-knowledge proofs are generally used to verify a prover's theorem to a verifier, in such a way that the verifier will not be able to discover any supplementary evidence other than the proof given to him. In this paper, we have reviewed different zero-knowledge argument / proof techniques. We have also reviewed the proof system implications in the presence of malicious prover and malicious verifier. We have removed the outliers of the experiment by using Mahalanobis distance. Examples associated to zero-knowledge argument systems are also given.
