Abstract

The invention relates to a blockchain technology, and discloses a method for verifying parameters of an encrypted data equivalence relationship. The method includes: after a first participant receives an encrypted data comparison request initiated by a second participant, sending a request to a second participant The participant provides verification parameters and certification parameters, wherein the verification parameters are generated by the first participant according to the first encrypted data [a], the second encrypted data [b] and the secret data, and are used to enable the second participant Compare whether the first original data a and the second original data b are equal; the second participant checks whether the verification parameter is generated according to the secret data according to the certification parameter. The invention also discloses an encrypted data peer relationship parameter checking device and a computer-readable storage medium. By using the present invention, the first participant can be prevented from providing false verification parameters, so as to ensure that the second participant can smoothly perform the peer-to-peer comparison of encrypted data.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, device and computer-readable storage medium for checking encrypted data peer-to-peer relationship parameters. Background technique [0002] Zero-Knowledge Proof (Zero-Knowledge Proof) was proposed by S.Gold wasser, S.Micali and C.Rackoff in the early 1980s. It refers to the ability of the prover to convince the verifier that a certain assertion is correct without providing any useful information to the verifier. A zero-knowledge proof is essentially an agreement involving two or more parties, that is, a series of steps that two or more parties need to take to complete a task. The prover proves to the verifier and makes him believe that he knows or has a certain message, but the proof process cannot leak any information about the proven message to the verifier. [0003] At present, in the zero-knowledge proof, if the comparison participant is required to c...
