Authentication method and system, server and client

Abstract

The invention relates to an authentication method, a system, a server and a client terminal. The authentication method comprises the steps: receiving an authentication request which contains client identifier, inquiring an authentication code corresponding to the prestored client identifier when the authentication request also contains the authentication code, testing the legality of the authentication code contained in the authentication request, instructing the client terminal to carry out security check according to the stored security configuration information after the authentication code contained in the authentication request passes through legality testing. The authentication method, the system, the server and the client terminal of the invention authenticate the authentication code contained in the authentication request, which avoids repeating authentication of the same authentication request to the authentication request with the same client identification information, simplifies authentication procedure, improves authentication efficiency, meanwhile instructs the client terminal to carry out security check according to the stored security configuration information, avoids repeat sending the same security configuration information, reduces the amount of data exchange between the server and the client terminal and is favorable for saving network band width resource.

Description

technical field [0001] The invention relates to the field of information security, in particular to an authentication method and system, a server and a client. Background technique [0002] Authentication systems are widely used in the field of information security. like figure 1 The authentication system corresponding to the authentication method shown is composed of a client and a server. The general process of using this authentication system for authentication is as follows: figure 1 Shown: [0003] Step a1, the client sends an authentication request including user identity information to the server; [0004] Step a2, the server receives the authentication request, performs identity verification on the user identity information included in the authentication request, and judges whether the user identity information is legal, and if the user identity information is legal, execute step a3; if the user identity information is invalid, execute step a6 ; [0005] Step a3...

AI Technical Summary

Problems solved by technology

At this time, adopting the existing authentication process will increase the load on the server and put forward higher requirements for the processing speed of the server and network bandwidth. If the processing speed and network bandwidth of the server cannot be guaranteed, there may be Causes network congestion and takes longer to complete the authentication process

Therefore, the existing authentication methods have technical defects such as large waste of network bandwidth resources and low authentication efficiency.
