Chaotic Cryptography for Wireless Communication

In recent years, the evolution of Internet of Things (IoT) communication has given rise to in creased security challenges. Encryption of IoT system information is deemed essential, with several protective systems identified, though concerns persist regarding their handling of large information capacities and redundancies. To address this, we introduce a novel switching frac tional chaotic system image encryption structure designed for three-dimensional diffusion and permuting pixels. This method enhances image scanning efficiency with a one turn, ensur ing high-quality diffusion of color and pixel positions. The proposed interleaved key stream generation approach effectively resists plain-text and differential attacks, focusing specifically on IoT image information encryption to ensure communication system security. A prototype implementation on the Raspberry Pi platform is provided. Another contribution of this paper is a comprehensive overview and analysis of ultra-low-power backscatter communication. The paper details how backscatter communication achieves a com plete communication chain in low-power communication solutions. Through simulation and analysis results, we confirm the feasibility of ambient backscatter communication under Phase Shift Keying (PSK) simulation. The integration of chaotic encryption systems and backscatter communication systems will be gradually completed in future work
