<P>PROBLEM TO BE SOLVED: To maintain an amount of physical random numbers which can be acquired by each process per unit time even if the number of processes simultaneously using the physical random numbers increases. <P>SOLUTION: When a plurality of processes acquire random numbers simultaneously, throughput of the random numbers available in all of the processes is improved by copying a random number on a memory and delivering it to each of the processes if no relation exists among the processes and if there is no problem even when a same random number is delivered to each of the processes. Meanwhile, if relations exist among the plurality of processes and if it is problematic to deliver a same random number, a driver for controlling such that random numbers different from each process can be delivered to the processes respectively according to a condition set by a user is prepared, thereby making uniqueness and speed of the random number compatible. <P>COPYRIGHT: (C)2012,JPO&INPIT |
