Such a protocol is useful in the case where one already has access to a private source for true randomness, but whose use is prohibitively expensive or whose access is limited. By applying randomness expansion, it is possible to make this resource go further using potentially much cheaper or more simple methods. | Such a protocol is useful in the case where one already has access to a private source for true randomness, but whose use is prohibitively expensive or whose access is limited.
