Abstract
A random number generating circuit includes M random number generators, where M is an integer greater than or equal to 2, configured to be independent of each other and generate M random number sequences, a delay adjustment circuit configured to output N sets of the M random number sequences including N different relative time differences or N different combinations of a plurality of relative time differences, where N is an integer greater than or equal to 2, by adjusting one or more relative time differences between the M random number sequences, and a logic operation circuit configured to perform an exclusive OR operation between the M random number sequences included in a set, for each of the N sets of the M random number sequences.
