Abstract (in Japanese) (See Japanese page) 
(in English) Pseudo-random numbers’ periodicity renders them inappropriate for use in cryptographic applications, but, naturally-generated physical-random numbers have no calculable periodicity, thereby making them ideally-suited to the task. Some experiments about physical-random number generation have reached to Gbps range by using laser diode’s (LD’s) intensity noises in recent years. The laser diode naturally produces a wideband “noise” signal that is believed to have tremendous capacity and great promise, for the rapid generation of physical-random numbers for use in cryptographic applications. The result shows that the fast physical-random number generation, as fast as 5Gbps, is obtainable, using the laser diode’s frequency noise characteristic.
