ABSTRACT:
A random number generating method and a random number generating device are provided which are capable of generating uniform random numbers. Random pulses are generated by comparing a voltage level obtained by amplifying a voltage level of a thermal noise produced by a thermal noise generating device with a reference voltage level. A pulse controller, if time intervals among random pulses are within a predetermined time, excludes random pulses occurred within the predetermined time and if time intervals among random pulses exceed the predetermined time, random numbers are generated based on time intervals among pulses measured by a counter.
