Problems solved by technology

[0006] The purpose of the present invention is to provide a more complete authentication mechanism for media gateways, to solve the problem that in the traditional MG authentication method, the third party is easy to forge the media gateway MG to initiate a call, and it is easy to forge the media gateway controller MGC to call the media gateway MG and the key The problem of being unchangeable for a long time that may be cracked by others can be authenticated for each call, and the shared key can be replaced regularly to effectively prevent illegal forged messages from calling it

Embodiment Construction

[0023] The invention discloses a method for using the MEGACO protocol to authenticate a media gateway MG, which includes the following steps:

[0024] Set the algorithm used to generate the shared key between the media gateway MG and the media gateway controller MGC as y=f 1 (x), set the algorithm used to generate the digital signature between MG and MGC as y=f 2 (x); the present invention does not limit the specific algorithm used.

[0025] The media gateway MG and the media gateway controller MGC are initially equipped with a key S for verifying the initial digital signature of both parties. The keys S of the media gateway MG and the media gateway controller MGC can be different, as long as the digital signature of the other party can be verified That's it; the transmission of the key and parameters can be realized by extending the MEGACO field or packet.

[0026] The media gateway MG first initiates a registration signaling registration to the media gateway controller MGC...

Abstract

The method includes following steps: initial cipher key is assigned for validating initial digital signature for both parties between media network gateway and media network gateway controller; media network gateway initiates registration signaling to media network gateway controller for registering together with parameters and digital signature for generating shared cipher key; media network gateway controller generates shared cipher key by using validated legal parameters and digital signature; the said controller sends generated parameters and digital signature and life time of shared cipher key setup through modifier command; media network gateway generates shared cipher key after validating validity of digital signature; in following each call and reply message, shared cipher key is utilized for signature and validating each other between media network gateway and media network gateway controller. Shared cipher key is updated regularly.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a media gateway authentication method realized through the MEGACO protocol. Background technique [0002] The Media Gateway Control (MEGACO) protocol is an RFC3015 protocol of the Internet Engineering Task Force (IETF for short). [0003] Such as figure 1 Shown is the network diagram of the system that implements the MEGACO protocol. The MEGACO protocol adopts the idea of ​​separating gateways, and decomposes the original signaling and media centralized processing gateway into two parts: Media Gateway (MG for short) and Media Gateway Controller (MGC for short). MGC controls the actions of MG through the MEGACO protocol: MGC sends commands to MG to be executed, MG executes and returns the result, and the media gateway controller MGC also processes the event request reported by the media gateway MG. The logical relationship in the MEGACO protocol is represented by a connec...
