Message verification method of communication network system, communication method and communication network system

Abstract

An embodiment of the present invention provides a message verification method of a communication network system, a communication method, and a communication network system. The method includes: the access control device receiving a communication establishment request sent by the first mobile device; The access control device sends a communication mutual authentication request to the authentication server in response to the communication establishment request; the access control device receives a mutual authentication response message sent by the authentication server in response to the communication mutual authentication request; the access The control device verifies the mutual authentication response message; when the mutual authentication response message is successfully verified, the access control device sends a mutual authentication message to the first mobile device, and utilizes the hash chain mechanism and access control The device cooperates with the authentication server to realize the distribution and decentralization of the authentication function, which reduces the load of the authentication server and improves the efficiency of authentication.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a message verification method of a communication network system, a communication method, a communication network system and a device. Background technique [0002] In the 5G (the 5th Generation mobile communication technology, fifth-generation mobile communication technology) network, there are communication methods such as D2D (Device to Device, device-to-device) communication and multi-hop connection communication, which can realize direct communication between mobile devices. The above-mentioned communication method complements the traditional communication method in which a mobile device connects to a base station, so as to increase the transmission rate between mobile devices and reduce the end-to-end delay. [0003] However, how to achieve mutual authentication between mobile devices is a key issue to ensure the security of communication between mobile devices...
