Abstract
A clock determination apparatus includes a signal wire and a clock determiner. A clock signal is input to the signal wire. A period made up of cycles corresponding to a predetermined number of cycles of the clock signal is referred to as a unit period. The clock determiner includes circuitry configured to perform determination processing whether the clock signal is a random clock signal including a cycle changing substantially irregularly as time proceeds or a regular clock signal including substantially a constant cycle based on a comparison between waveforms of the clock signals in a plurality of unit periods.
