Embodiment Construction

[0028] Functional Overview

[0029] In consideration of the hidden dangers of network security caused by the H.248 protocol using plaintext text messages for signaling interaction in related technologies, the embodiment of the present invention provides an authentication scheme, which uses MAC addresses and other information related to H. The conceptual content related to the .248 agreement, after a certain algorithm, obtains the authentication information used to check the legality of the registration. During the implementation of this solution, the MAC address of the terminal can be pre-configured on the SS side; the authentication method can be configured on the terminal and the SS, and a uniformly agreed algorithm can be used. Among them, the authentication method can be extended to a general authentication method by formulating and adopting a unified standard algorithm.

[0030] It should be noted that, in the case of no conflict, the embodiments in the present applicati...

Abstract

The invention discloses an authentication method. A soft switch receives a message from a terminal, wherein the message from the terminal comprises first authentication information generated by the terminal by adopting a predetermined algorithm according to an MAC address of the terminal and information in an H.248 media gateway control protocol and information in an H.248 protocol; the soft switch generates second authentication information by adopting the same algorithm with the predetermined algorithm according to the information in the H.248 protocol obtained in the message from the terminal and the MAC address of the terminal stored locally; and the soft switch passes the authentication of the terminal in the condition that the first authentication information is the same with the second authentication information. Through the invention, the reliability of the authentication information is ensured, and the safety of a network is enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to an authentication method, a soft switch and a terminal. Background technique [0002] At present, Voice over Internet Protocol (VoIP for short) has been widely used in fixed network operators' "optical into copper out" project, it uses the Internet for voice transmission, compared with the traditional public switched telephone network (Public Switched Telephone Network, referred to as PSTN), has a great price advantage in terms of networking costs, and fully exploits the functions of the data communication network (Internet). [0003] H.248 protocol (that is, Media Gateway Control Protocol, referred to as MEGACO protocol), as the main master-slave communication protocol in the VoIP protocol, has developed rapidly in recent years, and a large number of related products have been widely used Applications, for example, integrated access device (Integrated Access Device, referred t...
