Experimental Cryptanalysis of No-equilibrium Chaotic System Based Random Number Generator

Chaotic systems have to be carefully designed in critical applications. Therefore, these systems need high-quality cryptanalysis methods to make sure they work securely. In this paper, a three dimensional no-equilibrium chaotic system to produce random number bits is analyzed with giving numerical and experimental results. Generating random numbers/bits is vital in security systems since they require unpredictable values to keep the key securely for the attackers. The master-slave synchronization method is used to present the security weakness of the "novel" no-equilibrium chaotic system with hidden attractors. The no equilibrium chaotic system is analyzed with a scalar time series. The simulation and experimental results demonstrate that random number bits generated through the target chaotic system can be estimated because its randomness is based on deterministic sources.
