Authentication system and authentication method based on central node

Abstract

The invention discloses an authentication system based on a central node. The authentication system comprises local verification and authentication units and a remote verification and authentication unit; each of the local verification and authentication units includes a local authentication device; the remote verification and authentication unit includes an authentication central device; the authentication central device and a plurality of the local authentication devices are further respectively connected with a key relay device; the local verification and authentication units are connected to corresponding external devices. The invention further discloses an authentication method based on the central node. Compared with the prior art, through local verification and authentication or remote verification and authentication, on the basis of communication of authentication centers for the local verification and authentication and the remote verification and authentication, the communication connection between the external devices and all devices connected with the authentication centers is implemented by the authentication system and the authentication method, the defect that the external devices only can perform authentication with a designated device is abandoned, and the convenience is provided for multi-point authentication and communication; and in addition, the multi-encrypted transmission of authentication information is implemented in an authentication process, and the security for transmitting the authentication information is guaranteed.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to an authentication system and authentication method based on a central node. Background technique [0002] The access authentication device is the device closest to the access terminal, and is usually used to exchange messages with the authentication server, so as to forward the access request of the access terminal to the authentication server, so that the authentication server can perform network access authentication. [0003] Most of the traditional authentication methods are one-way, that is, the external device sends request information to the access authentication device, and the access authentication device performs verification after receiving the request information, and the external device can access after verification. The security of information transmission cannot be guaranteed, and the external device can only authenticate with the designated access aut...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a central node-based authentication system and authentication method to solve the one-way authentication of external equipment in the prior art, and the external equipment can only be authenticated with the designated access authentication equipment, resulting in insufficient information transmission security. Guarantee and the technical defect that the external device cannot communicate with multiple terminal devices at the same time
