Abstract
A method for correcting spatially variable electron flux in a true random number generator (TRNG) is presented. The TRNG comprises a radioactive source and an array of detectors, and the method comprises: (a) segmenting the array of detectors into a plurality of groups; (b) for each group: (1) detecting via multiple detectors an electron signal from the decay of the radioactive source; (2) determining a number of detections based on the detection of step (b)(1); (3) determining a group median count based on the number of detections; (4) comparing the group median count to either (A) a detection count from a single detector within the group, or (B) a detection count from multiple detectors within the group; (5) based on the comparison, assigning a value to a string of values; and (c) determining a true random number based on the string of values. A TRNG implementing the method is also disclosed.
