Zero-knowledge proof. In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover Peggy) can prove to another party (the verifier Victor) that she knows a value x, without conveying any information apart from the fact that she knows the value x.

Zero-knowledge proof

Another way of understanding this would be: Interactive zero-knowledge proofs require interaction between the individual (or computer system) proving their knowledge and the individual validating the proof.[1] If proving the statement requires knowledge of some secret information on the part of the prover, the definition implies that the verifier will not be able to prove the statement in turn to anyone else, since the verifier does not possess the secret information. Some forms of non-interactive zero-knowledge proofs exist,[2][3] but the validity of the proof relies on computational assumptions (typically the assumptions of an ideal cryptographic hash function).

Abstract examples[edit] Victor chooses an exit path , and. Preuve à divulgation nulle de connaissance. Une preuve à divulgation nulle de connaissance est une brique de base utilisée en cryptologie dans le cadre de l'authentification et de l'identification.

Preuve à divulgation nulle de connaissance

Cette expression désigne un protocole sécurisé dans lequel une entité nommée « fournisseur de preuve », prouve mathématiquement à une autre entité, le « vérificateur », qu'une proposition est vraie sans toutefois révéler d'autres informations que la véracité de la proposition.

Trusting personal information to online services makes us vulnerable to abuse.

What is Zero-Knowledge Encryption?

However, unless you’re an IT professional, it is very hard to understand what “safety” means for each service you use. If you want to make sure that you are truly protecting your private data – you should go for services that use Zero-Knowledge encryption. From this article, you will learn what “Zero Knowledge” is, how Zero-Knowledge encryption works and why we believe this is the best way you can protect your information online. In a nutshell, Zero-Knowledge encryption means that service providers know nothing about the data you store on their servers. But, to better grasp the term, let’s go over how encryption works in general.

A trip to the Zero-Knowledge Hotel Let’s imagine we are on a business trip. Now, let’s put it in context with our online usage: Because of encryption, the locks used by many cloud-based services are so strong that it would take huge computational resources to identify a single key. Cryptography - Zero-Knowledge Proofs. The goal is to prove a statement without leaking extra information, for example, for some N,xN,x, prove xx is a quadratic residue in Z∗N.

This allows us to define the following relation: Protocole d'authentification de Schnorr. En cryptographie, le protocole d'authentification de Schnorr (en) (souvent abrégé protocole de Schnorr) est une preuve à divulgation nulle de connaissance décrite en 1989 par Schnorr[1] dont la sécurité repose sur la difficulté du problème du logarithme discret et servant à prouver la connaissance d’un logarithme discret, c’est-à-dire étant donné , prouver que l'on connaît l'exposant engendré par.
