摘要
This paper introduces an algebraic cryptanalysis of a random number generator (RNG) based on a chaotic oscillator. An attack system is proposed to discover the security weaknesses of the chaos-based RNG. Convergence of the attack system is proved using master slave synchronization scheme 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. The RNG does not fulfill NIST-800-22, Diehard and Big Crush statistical test suites, the previous and the next bit can be predicted, while the same output bit sequence of the RNG can be reproduced.
