Analysis on the Security of Satellite Internet

Abstract

Satellite Internet (SI) is a new way to provide internet access all over the world. It will bring great convenience to international communication. Compared with the traditional communication networks, SI has a significant change in network architecture and communication model, which will have an important impact on national information network security. For example, the global interconnected SI consists of a large number of small satellites and each satellite has multi-beams to cover a vast area, which leads to the disorderly flow of information across the border, and greatly increases the difficulty of network protection. Therefore, it is necessary to closely track the development of SI and analyze security problems brought by SI. In this paper, we analyze the security risks of SI from the perspective of national security, network security and equipment security, and thirteen security issues have been summarized to provide reference for the healthy development of SI industry.

On the Security of LEO Satellite Communication Systems: Vulnerabilities, Countermeasures, and Future Trends

“…For example, most of the on-orbit satellites adopt the so-called bent-pipe 1 transponder without digital signal processing, so it is easy to encounter signal energy-based jamming attack. Attackers may easily perturb the satellite's operation by transmitting high-power jamming signals [97]. There are many types of jamming signals and classification methods.…”

A Survey on Authentication in Satellite Internet

“…attacks, replay attacks, impersonation attacks, and man-in-themiddle attacks. If the data in Satellite Internet was illegally accessed, eavesdropped, or tampered with, serious consequences may affect national security and social stability [9], [37]. Moreover, compared with traditional wireless networks, Satellite Internet has some special characteristics, such as extremely long propagation delay and limited on-satellite computing and storage capacity.…”
