Chaotic cascade systems enhance security of pseudo-random sequences
The article explores how combining chaotic systems in a cascade can enhance their sensitivity to initial conditions and randomness. By studying chaotic cascades, researchers found that the Lyapunov exponent of a cascade chaos system is the sum of its subsystems' Lyapunov exponents. This approach can improve the dynamic characteristics of chaotic systems like logistic, cubic, and tent maps, leading to better pseudo-random sequences with increased security and sensitivity to initial conditions.
