In cryptography, a proof of knowledge is an interactive proof where the prover demonstrates to a verifier that they possess specific information without revealing the information itself. This concept of "knowing something" is defined computationally, meaning a machine "knows" if it can compute the information given its input. The proof ensures that if the prover genuinely knows the information, they can convince the verifier, and no deceptive prover can convince the verifier without truly knowing the information.
