Abstract

See full text

A pseudo-random number generation device calculates a value st[i] of b[i] bits by using a function F[i] taking a value st[i−1] as input for each integer value i with i=1, . . . , n in ascending order. The pseudo-random number generation device calculates a value x[i] of r[i] bits by using a function g[i] taking as input at least a part of bits of a value st[j] and at least a part of bits of the value st[i] for at least a part of an integer value i with i=1, . . . , n, where a value j is an integer value smaller than the integer value i. The pseudo-random number generation device combines the values x[i] calculated by using the function g[i] to obtain a pseudo random number.
