SM2-based secret key exchange method, system, electronic equipment and storage medium

Abstract

The invention provides an SM2-based secret key exchange method, a server, terminal equipment, a system, electronic equipment and a storage medium, relates to the technical field of computers, and specifically relates to artificial intelligence and a blockchain technology. The SM2-based secret key exchange method comprises the steps of: receiving random information transmitted by second electronicequipment; receiving secret key information transmitted by equipment participating in secret key exchange; generating a first secret key component according to the random information, the secret key information, a secret key fragment of the first electronic equipment and a preset public key; generating argumentation information according to the first secret key component; and transmitting the first secret key component and the argumentation information to the second electronic equipment. On one hand, the argumentation information used for verifying the identity of the first electronic device is generated according to the first secret key component, the technical effects of theft prevention and attack prevention are achieved, and therefore the technical effect of ensuring the safety of userinformation is achieved; and on the other hand, the first electronic equipment and the second electronic equipment are combined to jointly realize secret key exchange, so that the technical effect ofimproving the safety and reliability of secret key exchange can be achieved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to artificial intelligence and blockchain technology, and in particular to an SM2-based key exchange method, server, terminal equipment, 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 based on the server or terminal device, the key exchange is performed with other devices, then the attacker can obtain the private key through privilege escalation, and exchange the secret key based on the private key . [0004] However, in the process of implementing this application, the inventor found ...
