Embodiment Construction

[0048] Here, two embodiments of the secure transmission method for broadband wireless multimedia network broadcast communication of the present invention are given.

[0049] Referring to Fig. 1, the specific steps of Embodiment 1 of the present invention are as follows:

[0050] 11) Using the PKM2 protocol of IEEE802.16e, a trust relationship is established between large and small base stations to form a secure channel;

[0051] 11.1) When building a network, first run the RSA-based authorization protocol or EAP authentication protocol between the large and small base stations to complete the identity authentication and authorization key AK between the large and small base stations BBS-CBS (AuthorizationKey) negotiation, wherein the application of the EAP authentication protocol also requires the participation of the AAA server;

[0052] 11.2) Based on the authorization key AK BBS-CBS , the large and small base stations negotiate and distribute the service encryption key TEK...

Abstract

The invention relates to a secure transmission method of wide band wireless multimedia network broadcast communication; the method comprises the following steps: 1) trust relationship is established between big base stations and small base stations and a secure channel is formed; 2) the big stations distributes an encryption key of the broadcast communication to each small base station secretly by the secure channel; 3) when users log on the small stations, the encryption key of the broadcast communication of the big base stations can be obtained after passing certificate authority. The invention solves the problem that the broadcast communication of the big base stations without an uplink channel is not secure when working in a mode of mixed covering of large and small areas, thus realizing the identification of users and the base stations and ensuring that only the authorized users can receive broadcast service.

Description

technical field [0001] The invention relates to a safe transmission method of broadband wireless multimedia network broadcast communication. Background technique [0002] BWM (Broadband Wireless Multimedia networks) aims to seek a technical approach with high operating efficiency and low cost, and comprehensively achieve the "three The overall goal of "network convergence". [0003] The BWM network is a new type of broadband wireless mobile network that combines the technical features of the mobile TV network and the broadband wireless access network. At the same time, it is different from the broadband wireless access network and the mobile TV network. The BWM network can be configured with a powerful IP core network and integrated service management platform, and the same operation and maintenance support platform is configured for different terminal services. In terms of wireless access network architecture, the BWM network fully considers the networking characteristics...
