A safety certification method, device and system for a client end

Abstract

The invention discloses a safety certification method for a client end. The method comprises: acquiring authentication information for executing safety certification for the client end; sending the authentication information to a certification center; and when a first response message returned by the certification center is received, reacquiring the authentication information, resending the reacquired authentication information to the certification center, and executing safety certification for the client end according to the reacquired authentication information by the certification center. Meanwhile, the invention also discloses another safety certification method for a client end, a safety certification system for a client end, a mobile terminal, and a certification center. Adopting the safety certification method, device and system for a client end, safety certification can be executed for the client end by establishing a unified certification center for the client end; and it can be realized that safety certification is executed for the client end without connecting the mobile terminal to any external equipment or changing any internal software of the mobile terminal.

Description

technical field [0001] The invention relates to security authentication technology in the field of wireless communication, in particular to a client security authentication method, device and system. Background technique [0002] At present, the security authentication method for the mobile terminal client is to transplant the traditional WEB-side e-commerce certificate authority (Certificate Authority, CA) authentication to the mobile terminal client. This method has two prerequisites: [0003] 1) Install a specific ultra-small and large-capacity mobile storage (Tran Flash, TF) card on the mobile terminal, and the TF card contains user authentication information; [0004] 2) Install specific CA software in the mobile terminal system. [0005] The specific implementation process of security authentication is as follows: [0006] Step 1: Start a certain application client on the mobile terminal; [0007] Step 2: automatically start the CA software installed in the mobile t...

AI Technical Summary

Problems solved by technology

[0012] 1) It is necessary to install a specific TF card or other hardware device containing user authentication information, which is cumbersome to operate;

[0013] 2) Different application clients need to deploy a specific CA authentication server, and the cost is relatively high;

[0014] 3) The information security of the mobile terminal client cannot be guaranteed when the mobile terminal is lost;

[0015] 4) Access to the CA authentication server needs to be relayed through VPN, which reduces the access efficiency of mobile terminals
