Generally, this disclosure describes a system and method for generating random numbers. In at least one embodiment described herein, the method may include generating random bits in accordance with at least one security application via an integrated circuit, said integrated circuit including a true random number generator having an analog core. The method may further include providing, via an internally generated power supply, power to said analog core via a voltage regulator associated with said true random number generator. Of course, additional operations are also within the scope of the present disclosure.
