Embodiment Construction

[0108] The present invention will be further described below in conjunction with the description of the drawings and specific implementations:

[0109] Such as Figure 3-9 The safety mechanism management method based on the DTN interactive satellite distance education system shown includes the following steps:

[0110] A. Key distribution, node authentication and information encryption:

[0111] A1. When the satellite receiving terminal is deployed, the conditional access module CAM pre-registers the smart card for the user, so that the broadcast server and each terminal node have a dedicated shared symmetric key that is the conditional access key KEY;

[0112] A2. Establish the key distribution server and IPDTN gateway so that the key distribution server, IPDTN gateway and broadcast server belong to the same trusted domain and are located in the satellite broadcast center. Register the ID and ID of each satellite receiving terminal in the key distribution server. Its conditional acc...

Abstract

The invention discloses a DTN (Delay Tolerant Network)-based security mechanism management method for an interactive satellite remote education system. The DTN-based security mechanism management method is characterized by comprising the following steps that: the key distribution, node authentication and information encryption are carried out; the encryption and authentication of terminal nodes are carried out; the authentication of mobile communications nodes is carried out; the IPDTN gateway authentication is carried out; a key distribution server assists a system in completing the encryption and authentication; and a satellite broadcast server assists the system in completing the encryption and authentication. The DTN-based security mechanism management method for the interactive satellite remote education system, disclosed by the invention, has the advantage that the deficiencies in the prior art are overcome.

Description

Technical field [0001] The invention relates to a safety mechanism management method based on a DTN interactive satellite distance education system. Background technique [0002] The distance education system based on IP over DVB-S provides support for the realization of educational informatization and sharing of educational resources in remote areas such as agricultural and pastoral areas. However, the one-way nature of satellite broadcasting limits the teaching mode and cannot meet the needs of end users for interactive applications. [0003] End users hope that the interactive services provided by the satellite distance education system are mainly divided into the following three categories: 1. Content services, users can subscribe to their favorite educational resources and customize satellite distribution content; 2. Teaching services, including homework Q&A, network examinations and Checking papers, etc.; 3. Personalized services, such as art works display, personal resource...
