Key generation method, system, mobile terminal, server and storage medium

Abstract

The disclosure relates to a key generation method, system, mobile terminal, server and storage medium. The method includes: the mobile terminal sends a registration request including the mobile phone number of the target user to the server; the server receives the registration request and sends the mobile phone number of the target user Send the registration verification code; the mobile terminal receives the registration verification code in response to the registration request and uses the registration verification code and the mobile phone number used to generate a user key pair, and sends the public key in the user key pair to the server; the server utilizes the target The user's mobile phone number and the issued registration verification code generate the user's public key and compare it with the public key in the user's key pair, and return the comparison result to the mobile terminal; if the comparison result indicates that the user's key pair The public key in is consistent with the user public key, and the mobile terminal determines that a user key pair for verifying the identity of the target user has been successfully generated. Through the technical solution of the present disclosure, it can ensure that the user key pair is generated on the mobile terminal held by the target user.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a key generation method, system, mobile terminal, server, and storage medium. Background technique [0002] With the development of mobile Internet technology and the advancement of smart mobile terminal applications, mobile terminals such as mobile phones have become indispensable smart devices for mobile office applications. network activity. In these Internet applications, user identity authentication is particularly important, and reliable user identity identification is usually implemented using a key-based digital certificate, which requires the user to hold a key for signature calculation. [0003] In the prior art, considering the portability of the mobile terminal, it cannot be easily connected to an external cryptographic device like a computer to ensure user identity and data security, and most mobile terminals do not have built-in and integrated ...

Problems solved by technology

[0003] In the prior art, considering the portability of the mobile terminal, it cannot be easily connected to an external cryptographic device like a computer to ensure user identity and data security, and most mobile terminals do not have built-in and integrated security cryptographic hardware, usually Generate a key for the user in the mobile terminal and store it

However, the existing key generation method cannot ensure that the mobile terminal that initiates the registration request and the mobile terminal that finally generates the user key are the same terminal, and also cannot ensure that the same mobile terminal is the same when initiating the registration request and generating the user key. same phone number used
