PROBLEM TO BE SOLVED: To obtain a chaotic random number generator considering periodicity which easily obtains the random number of the chaotic orbit of long periodwith strict repeatability in spite of the restriction of a compiler and a hardware. SOLUTION: This generator obtains a random number by generating chaotic orbital values X2 , X3 ,... from an initial value X1 by using a mapping X1+x =f(Xi) in a chaotic area. At the time of executing mapping the initial value X1 to X2 , X2 to X3 , the chaotic orbital value is obtained by executing arithmetic related with mapping by arithmetical operation in an integer area by every one position and carry arithmetic through the use of the number of N pieces of the figures of the orbital value, of register groups 15 and 16 and 2N pieces of register groups 17 and 18. |
