Abstract: A device for providing a random number generator is provided. The device may include a true random number generator, at least one deterministic random number generator, and an exclusive OR logic function. The TRNG has an output and the at least one DRNG has an output. The exclusive OR logic function has a first input coupled to the output of the TRNG and a second input coupled to the output of the at least one DRNG, and an output for providing a random number. The TRNG and the at least one DRNG may include separate and independent entropy sources. A method for generating a random number is also provided.
