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

Abstract

The invention relates to a key generation method, a system, a mobile terminal, a server and a storage medium. The method comprises the following steps: a mobile terminal sends a registration request including a mobile phone number of a target user to a server. The server receives the registration request and sends the registration verification code to the mobile phone number of the target user. The mobile terminal receives a registration verification code for responding to the registration request, generates a user key pair using the registration verification code and the used mobile phone number, and sends a public key in the user key pair to the server. The server generates a user public key by using the mobile phone number of the target user and the registration verification code sent out, compares the user public key with the public key in the user key pair, and returns the comparison result to the mobile terminal. If the comparison result indicates that the public key in the userkey pair is consistent with the user public key, the mobile terminal determines that the user key pair for verifying the identity of the target user is successfully generated. With the technical solution of the present disclosure, it can be ensured that a user key pair is generated at a mobile terminal held by a 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
