Lyapunov exponent: Towards randomness measure

We propose a method based on Lyapunov Exponente (LE) capable of measuring randomness of PRNGs (pseudo-random number generators). We study PRNG as discrete dynamical system, motivated by the strong relation between chaos and randomness. Results show good discrimination among PRNG parameters.This extended abstract was presented by Jeaneth Machicao at 2nd Satellite Meeting on Complex Behaviour in Discrete Dynamical System part of European Conference on Complex Systems (ECCS'12), 201
