Abstract
A random bit stream generator includes a plurality of feedback shift registers configured to store a plurality of bit values that represent an internal state of the random bit stream generator. Each feedback shift register includes a register input and a register output. The random bit stream generator further includes a Boolean output function configured to receive the plurality of register outputs from the plurality of feedback registers, to perform a first Boolean combination of the plurality of register outputs, and to provide a corresponding output bit, wherein a plurality of successive output bits forms a random bit stream. A feedback loop is configured to perform a second Boolean combination of the output bit with at least one register feedback bit of at least one of the feedback shift registers, so that the register input of the at least one feedback shift register is a function of the output bit.
