Abstract A novel non‐autonomous continuous‐time chaotic oscillator suitable for high‐frequency integrated circuit realization is presented. Simulation and experimental results, verifying the circuit feasibility, are given. Two methods for using this oscillator as the core of a random number generator are also proposed. Numerical binary data obtained according to the proposed methods pass the four basic tests of FIPS‐140‐2, while experimental data pass the full NIST‐800‐22 random number test suite.
