Research on autonomous game for security of satellite Internet of Things based on embodied large models

As a key infrastructure for global seamless connectivity, space-based IoT has significant value in military and civilian fields, but faces multi-dimensional security threats in spectrum layer, physical layer, protocol and payload layer. The existing defense systems are difficult to meet the dynamic attack and defense needs due to problems such as static encryption being easily broken and centralized architecture having single-point failure risks. The combination of embodied large model and autonomous game theory provides a new idea to solve this problem: the embodied large model can integrate multi-modal data to realize real-time cognition of complex space environment, and autonomous game can simulate the interaction of attack and defense strategies and solve the optimal defense strategy. By constructing an embodied large model adaptation framework and a security autonomous game model, combined with measured data and simulation verification, this paper proposes a new paradigm for space-based IoT security protection, providing sustainable guarantee for the improvement of anti-destruction in strong confrontation environments.
