Abstract

The invention provides an SM2-based signature method, terminal equipment, a server, a system, electronic equipment and a storage medium, relates to the technical field of computers, and specifically relates to artificial intelligence and a block chain technology. The SM2-based signature method comprises the following steps of: receiving random information corresponding to to-be-signed informationtransmitted by second electronic equipment; determining a commitment component of a signature result according to the random information; generating argumentation information according to the commitment component; generating an attestation component of first electronic equipment used for signature according to the commitment component and the to-be-signed information; and transmitting the argumentation information and the attestation component of the first electronic equipment to the second electronic equipment. On one hand, the argumentation information is generated, the information of the first electronic equipment is prevented from being stolen, and the technical effect of ensuring the safety of user information (including personal information, financial related information and the likeof a user) is achieved; and on the other hand, the first electronic equipment and the second electronic equipment are combined to sign together, so that the technical effect of improving the safety and reliability of signing can be achieved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, specifically to artificial intelligence and blockchain technology, and in particular to an SM2-based signature method, terminal equipment, server, system, electronic equipment, and storage medium. Background technique [0002] With the development of Internet technology, the security and reliability of information transmission or storage has become the focus of attention. [0003] In the prior art, a server or a terminal device usually stores and uses a private key in the form of software. For example, if the private key is completely stored in the server or terminal device, and the information to be signed is signed based on the server or terminal device, then the attacker can obtain the private key through privilege escalation and sign according to the private key. [0004] However, in the process of implementing the present application, the inventors found at least the following pr...
