Title:
METHOD FOR GENERATING RANDOM NUMBER AND RANDOM NUMBER GENERATOR
Document Type and Number:
Japanese Patent JP2004127217
Kind Code:
A
Abstract:

To provide a novel method for generating more disordered random numbers by using an apparatus of inexpensive and simple configuration, and to provide the apparatus to be applied for the method.

During the rise time from oscillation start to steady state, an electric signal oscillated from an oscillation circuit 40 is inputted to an A/D converter 50, and the electric signal is converted into digital voltage components according to the magnitude of the amplitude thereof. Next, the digital voltage components are inputted to a personal computer 60. In the personal computer 60, a threshold for the digital voltage components is set, the magnitude relation between the digital voltage components and the threshold is determined, and a numeral "0" or "1" is allotted, thereby to generate a binary random number.
