Abstract

This paper proposes a novel 5-dimensional hyperchaotic coupling synchronization system for physical layer security in OFDM satellite systems. The proposed approach is designed based on the Lyapunov stability theory. The proposed chaotic-based satellite data encryption/decryption system is validated using a numerical simulation study. Additionally, to demonstrate the efficiency of the proposed chaotic encryption structure, we analyzed its key space. The proposed chaotic encryption structure is very sensitive to the initial key, and a tiny discrepancy as small as 10−19 would lead to a completely different sequence. The key space of the proposed scheme is up to 10³⁴⁰.
