Abstract

According to example embodiments of the present disclosure, a method, an electronic device, and a computer storage medium for generating a data equivalence zero-knowledge proof are provided. In this method, at the data side device, the target data is divided into N data blocks, and based on the N data blocks and predetermined N+1 elliptic curve base points, the first random number and the second random number, the target data is generated The first data label and the second data label of , based on the third random number, the fourth random number and N fifth random numbers and the predetermined N+1 elliptic curve base points, the first commitment, the second commitment, the N experience The data block of the random challenge, the first random challenge number and the second random challenge number are sent to the verifier device together with the first data label and the second data label as a zero-knowledge proof equivalent to the data label. Therefore, the present invention can zero-knowledge verify whether the data corresponding to two data tags are equivalent without revealing the plaintext of the data.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of information processing, and specifically relate to a method for generating a zero-knowledge proof of data equivalence, a method for verifying data equivalence, an electronic device, and a computer storage medium. Background technique [0002] Data management through blockchain is a common scenario of blockchain. Most of the traditional solutions perform hash operations on the data to obtain the abstract value of the data, and then use the abstract value as the label of the data and submit it to the blockchain for storage. Since the hash operation is a deterministic operation, the same data will get the same hash value, so there is a risk of leaking confidential information on the chain. Contents of the invention [0003] Embodiments of the present disclosure provide a method for generating a data equivalence zero-knowledge proof, a method for verifying data equivalence, an electr...
