Method, system, device, processor and storage medium for information encryption matching

Abstract

The invention relates to a method for realizing information encryption matching processing based on an SM2 curve, and relates to an information encryption matching module owned by an initiator, a response end and the two ends respectively. The initiator generates mapping information, and performs blinding processing to generate blinding information. The responder performs blind signing processing to generate blind signing information. The initiator removes the blinded information to obtain the encrypted information to be matched. The responder generates mapping information, encrypts and generates encrypted information to be matched. The initiator compares the encrypted information to be matched by itself with the encrypted information to be matched received from the responder, and judges whether they match. The invention also relates to a system, device, processor and computer-readable storage medium for information encryption matching processing. The method, system, device, processor and computer-readable storage medium for implementing information encryption matching processing based on the SM2 curve of the present invention not only realize the randomness of encryption matching information, but also have high encryption strength and fast processing speed advantage.

Description

technical field [0001] The present invention relates to the field of computers, in particular to the field of computer security, and specifically refers to a method, system, device, processor and computer-readable storage medium for realizing information encryption matching processing based on SM2 curves. Background technique [0002] Cooperation between business organizations often requires sharing and exchanging information. Before sharing and exchanging, one hopes to know what needs to be shared and exchanged and what cannot be shared and exchanged. This creates a paradox in the general case: without sharing there is no way of knowing what cannot be shared. [0003] In order to solve this problem, cryptographic hash functions are widely used among institutions to irreversibly convert information, and then match to find out the same part, and to achieve the purpose of confidentiality because different parts cannot be reversed. [0004] However, there is a defect in simply...

Problems solved by technology

[0004] However, there is a defect in simply adopting a cryptographic hash function: since the hash information generated by the same information is also the same, the hash information can be collided

[0007] The message encryption matching method implemented with the RSA public key cryptography algorithm has higher security than the message encryption matching method simply using the password hash function. One party generates the RSA public key and private key, and adds a random mask to the other party. The RSA public key encrypted message is blindly signed, and the other party matches the encrypted signature message after deblinding, which is more secure than the message encryption matching method that simply uses a password hash function, but it is difficult to use under high encryption strength. achieve satisfactory performance

[0008] The prior art also proposes a blind signature scheme based on the SM2 curve, which satisfies the protection of the privacy of the user and the verifiability of the signature of the signer, but cannot meet the requirements of message encryption matching between partners.
