What are Zero Knowledge Proofs? - Decrypt

In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true while the prover avoids conveying any additional information apart from the fact that the statement is indeed true. The essence of … See more The Ali Baba cave There is a well-known story presenting the fundamental ideas of zero-knowledge proofs, first published in 1990 by Jean-Jacques Quisquater and others in their paper "How to … See more Different variants of zero-knowledge can be defined by formalizing the intuitive concept of what is meant by the output of the simulator "looking like" the execution of the real proof … See more Authentication systems Research in zero-knowledge proofs has been motivated by authentication systems where one party wants to prove its identity to a second party via … See more A zero-knowledge proof of some statement must satisfy three properties: 1.
