Abstract

The embodiment of the invention discloses a circuit-based data verification method and device and an electronic device, and the method comprises the steps of splitting a target circuit into a plurality of mutually independent function modules, and generating a proving key and a verification key of each function module; sending the functional module and the proving key of each functional module toa proving party; receiving sub-output data, sub-input data and proof information of each functional module obtained by the proof party based on target data, the functional module and a proof key of each functional module, and output data of the target circuit based on the target data; verifying the sub-output data, the sub-input data and the proof information of each functional module according tothe verification key of each functional module, and verifying the output data to determine whether the proof party holds the target data or not. Through the method, the zero-knowledge proving processbased on the circuit can be shortened, and the verification efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a circuit-based data verification method, device and electronic equipment. Background technique [0002] With the continuous development of electronic technology, the circuits used by people are getting bigger and bigger, and the circuit structure is becoming more and more complex. The privacy issues based on large circuits have also attracted more attention. People combine zero-knowledge proofs with circuits. It is possible to convince the other party that it holds the secret data without revealing the secret data it holds. [0003] The zero-knowledge proof based on a large circuit means that the verifier generates a key pair for the entire circuit, and then sends the circuit and the key pair to the secret holder (that is, the prover), and the prover inputs the secret data into the circuit, The data and proof information are obtained through circuit calculation, and the pro...
