Embodiment Construction

[0032] At present, the implementation schemes of PSI mainly include the implementation scheme based on the hash algorithm, the implementation scheme based on the key exchange algorithm (Diffie Hellman, DH) and the public key encryption algorithm (Rivest Shamir Adlemen, RSA) blind signature, and the implementation scheme based on the Bloom filter. (Bloom Filter, BF) implementation schemes and implementation schemes based on inadvertent polynomials, etc., although these PSI implementation schemes can obtain the intersection data between the plaintext data of both parties to a certain extent, but these PSI implementation schemes have some The disadvantages are as follows:

[0033] 1. Hash-based PSI implementation.

[0034] Since both parties use the same hash algorithm when encrypting their plaintext data in the process of obtaining intersection data, the ciphertext data of both parties can be easily cracked, resulting in the plaintext data of both parties being easily leaked , ...

Abstract

The invention discloses a data processing method, a system, a device, an apparatus and a medium, which are applied in the technical field of data processing to solve the problems of data leakage and the like. Specifically, for each piece of plaintext data in the first plaintext of the first communication terminal and the second plaintext of the second communication terminal, The public key ciphertext data is obtain by using the public key encryption, a first setting portion of public key ciphertext data is encrypted using a first private key of a first communication terminal, the first privatekey ciphertext data set of the first plaintext and the second private key ciphertext data set of the second plaintext are obtained by encrypting the second setting part of the public key ciphertext data with the second private key of the second communication terminal, and the intersection data is obtained by using the first private key ciphertext data set and the second private key ciphertext data set. As such, since that first communication terminal and the second communication terminal only have a public key and a private key, neither of the first communication terminal and the second communication terminal can decrypt the plaintext data of the other party, the plaintext data is difficult to leak, and the data security is high.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method, system, device, equipment and medium. Background technique [0002] With the rapid development of computer networks, Private Set Intersection (PSI), as an emerging research field in recent years, has attracted more and more attention. Among them, PSI is a technology to calculate the intersection data between the plaintext data of both parties without revealing the plaintext data of either party. [0003] At present, although there are many implementation schemes of PSI, the security of these implementation schemes of PSI is not very high, private data is easily leaked, and the accuracy of the obtained intersection data needs to be improved. Contents of the invention [0004] Embodiments of the present invention provide a data processing method, device, system, equipment, and medium to solve problems such as poor data security and low a...
