Cryptographic proof meaning

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 zero-knowledge proofs is that it is trivial to prove that one possesses knowledge of certain information by simply revealing it; the challenge is to prove such possessio… WebThe meaning of "hard" The basic question is the meaning of "hard". There are two approaches to answer this question. First is the intuitive/practical approach: "hard means that it is almost certainly beyond the reach of any adversary who must be prevented from breaking the system for as long as the security of the system is deemed important."

WebA cryptographic hash function should be computationally efficient, meaning that it must be quick in performance to create the hash value. It has to be deterministic - every time you put in a certain input, it has to produce the same output and to be pre-image resistant which means it cannot reveal any information about the input in the output. WebThe goal is to prove a statement without leaking extra information, for example, for some N, x, prove x is a quadratic residue in Z ∗ N. Let L ⊆ Σ ∗. A zero-knowledge proof system for L …
