A chaos-based pseudo random number generator using timing-based reseeding method

In this paper, a 32-bit chaos-based pseudo random number generator (PRNG) using timing-based reseeding method with pure digital pseudo noise is proposed for passing the SP 800-22 test. In the iterations of the given chaos equation, when the reseeding timing arrives, the last five least significant bits of the iteration result are masked to produce the pseudo noise, and then the masked result is feedback to the iteration process as a new seed. Using this reseeding method, the proposed PRNG would result in an acceptable quality of randomness without operating in longer bit length digital operation
