Abstract: A true random number generator is presented that includes a CMOS matrix detector with a top surface. A shell is positioned over the top surface, and the shell includes a radiation source and a luminophore or scintillator constructed to emit photons towards the top surface when the luminophore or scintillator is struck by electrons from the radioactive decay of the source of the radiation. The CMOS detector matrix is constructed to detect the photons emitted from the luminophore or scintillator and to produce a signal for the detected photons. The signal is communicated to a processor that produces true random numbers based on the signal from the detected photons.

Abstract: Methods are disclosed for manufacturing a true random number generator (TRNG), wherein the TRNG includes a cavity filled with tritium and an electronic sensor constructed to detect energy from the decay of the tritium. One method includes (a) forming the cavity by bonding an enclosing structure to the sensor or adjacent to the sensor such that a portion of the sensor forms an inner surface of the cavity, (b) injecting the tritium gas into the cavity via one or more ports in the enclosing structure, and (c) sealing the one or more ports. Another method includes (a) applying a drop of tritiated water or tritiated gel to a surface of the electronic sensor, and (b) applying epoxy over the drop of tritiated water or tritiated gel (prior to step (b), the surface of the electronic sensor may be cooled sufficiently to freeze the drop of tritiated water or tritiated gel).

Abstract: Disclosed herein is a true random number generator (TRNG). The TRNG includes an enclosure defining a cavity and a cap covering the cavity and having a cap surface exposed to the cavity, the cap surface including radioactive nickel. An electronic sensor within a cavity detects electrons from the decay of the nickel and produces a signal for the detected energy. An amplifier is connected to the sensor and constructed to amplify the signal and feeds the signal to a filter. A processor connected to the filter generates a true random number based on the signal. This TRNG may be formed on an integrated circuit.
