Chaos-driven encryption of biomedical EEG using fractional-order memristive dynamics and random quantization
This paper presents a complete EEG encryption framework based on a newly designed fractional variable order memristive hyperchaotic system. The proposed system exhibits high dimensional nonlinear dynamics with tunable memory effects, making it highly suitable for cryptographic operations requiring strong sensitivity, unpredictability, and large keyspace. A nonlinear keystream generator is constructed using chaotic...
