Summary:
This paper introduces security analysis of a chaos based random number generator (RNG). An attack system is proposed to discover the security weaknesses of the chaos-based RNG. Convergence of the attack system is proved using auto-synchronization scheme (synchronization with unknown parameters). Secret parameters of the RNG are recovered from a scalar time series where the only information available are the structure of the RNG and a scalar time series observed from the chaotic oscillator. Simulation and numerical results verifying the feasibility of the attack system are given. It is shown that deterministic chaos itself cannot be pointed out as the source of randomness.
