Novel security architecture of satellite communication network

Abstract

In satellite communication networks, some malicious users may share illegal information. This communication makes the network be insecure. In order to cut off the illegal communication while maintaining the legal communications as many as possible, this paper propose a novel satellite communication security architecture. In this architecture, the satellites are divided into two layers. The satellites in the first layer are in charge of cutting off the illegal communication. The satellites in the second layer are normal communicating satellites communicating with each other.
