"WebBy "computationally infeasible", we mean non polynomial time and memory and by "distinguish", we mean that the probability to take the good decision is significantly greater than 1/2. Random bits produced by peripherals events (e.g. by Entropy Gathering Daemons ), or by HAVEGE, are not, strictly speaking, truly random bits nor pseudo-random bits. " - Havege algorithm
