Dynamically Optimize MTD Strategy in Satellite Computing Systems Using A2C Reinforcement Learning

Lin Zhang, Yunchuan Guo, Shoukun Guo, Fenghua Li, Faqun Jiang, Liang Fang
ICASSP 2025accepted

The Satellite Computing System (SCS) faces an increasing number of attacks. Although Moving Target Defense (MTD) can effectively mitigate attacks in ground networks, it is not well-suited for SCS due to the highly dynamic nature of both SCS traffic and attackers’ scanning behaviors. In this paper, w…

SEHAP: Secure and Efficient Handover Authentication Protocol in LEO Satellite Non-Terrestrial Networks

Yunchuan Guo, Jing Wang, Kui Geng, Zifu Li, Fenghua Li, Liang Fang
ICASSP 2025accepted

LEO satellite non-terrestrial networks (NTN) utilize satellites in Low Earth Orbit (LEO) to dynamically establish global communication service and own significant promise. The dynamic nature of LEO satellite NTN necessities efficient handover authentication protocols. However existing schemes cannot…
