A method and system for obscuring the internal state of a random number generator. The method includes a random number generator generating a first plurality of bits, wherein the first plurality of bits includes at least one data bit and at least one protection bit. A logic function (e.g. an exclusive OR) function may be performed on the first plurality of bits. Performing the logic function on the first plurality of bits may generate a second plurality of bits, which may then be output by the random number generator. The internal state of the random number generator may be obscured by using the logic function to generate the second plurality (i.e. output) of bits from the first plurality of bits.
