  2. Zero-knowledge proof - Wikipedia

    en.wikipedia.org/wiki/Zero-knowledge_proof

    This is called a "zero-knowledge proof of knowledge". However, a password is typically too small or insufficiently random to be used in many schemes for zero-knowledge proofs of knowledge. A zero-knowledge password proof is a special kind of zero-knowledge proof of knowledge that addresses the limited size of passwords. [citation needed]

  3. Non-interactive zero-knowledge proof - Wikipedia

    en.wikipedia.org/wiki/Non-interactive_zero...

    Using different commitment schemes, this idea was used to build zero-knowledge proof systems under the sub-group hiding [38] and under the decisional linear assumption. [39] These proof systems prove circuit satisfiability, and thus by the Cook–Levin theorem allow proving membership for every language in NP. The size of the common reference ...

  4. Zero knowledge - Wikipedia

    en.wikipedia.org/wiki/Zero_Knowledge

    Zero knowledge may mean: Zero-knowledge proof , a concept from cryptography, an interactive method for one party to prove to another that a (usually mathematical) statement is true, without revealing anything other than the veracity of the statement

  5. Zero-knowledge password proof - Wikipedia

    en.wikipedia.org/wiki/Zero-knowledge_password_proof

    A common use of a zero-knowledge password proof is in authentication systems where one party wants to prove its identity to a second party using a password but doesn't want the second party or anybody else to learn anything about the password. For example, apps can validate a password without processing it and a payment app can check the ...

  6. Fiat–Shamir heuristic - Wikipedia

    en.wikipedia.org/wiki/Fiat–Shamir_heuristic

    The Fiat–Shamir heuristic thus demonstrates a major application of random oracles. More generally, the Fiat–Shamir heuristic may also be viewed as converting a public-coin interactive proof of knowledge into a non-interactive proof of knowledge. If the interactive proof is used as an identification tool, then the non-interactive version can ...

  8. Proof of knowledge - Wikipedia

    en.wikipedia.org/wiki/Proof_of_knowledge

    In cryptography, a proof of knowledge is an interactive proof in which the prover succeeds in 'convincing' a verifier that the prover knows something. What it means for a machine to 'know something' is defined in terms of computation.
