A Secure Satellite Remote Education System for Agricultural and Pastoral Areas Based on IPv6

Abstract

This paper proposes a satellite remote education system based on IPv6 due to the lack of network infrastructure in agriculture and pasturing areas. The system combines satellite network with DTN in order to deliver educational resources to the users in the farming and pastoral areas. In the special DTN of agricultural and pastoral areas, a new bundle encapsulation method is designed, which combines IPv6 and DTN. An endpoint can be identified by its IPv6 address and we propose a corresponding data transmission protocol for the network of IPv6 over DTN. We implement an interactive distance education system through reverse transport mechanism, DTN users can send their resource subscription information to the server. A security policy and a bundle authentication process are proposed to ensure the security of the DTN and the entire education system.
