Abstract
A random number generating method includes sending a signal source for outputting a data sequence and randomly retrieving a segment of data having an operation length as a seed; converting the seed into a first operation value, determining whether a difference between the first operation value and a second operation value is larger than a threshold value, and determining whether a total number of times the first operation value has been inputted into the operation value processing step is larger than a predetermined value. The first operation value is reset by a reset algorithm; otherwise the sample selection step is re-performed. The operation values are converted into a random number. A total number of bits of the random number is calculated. The operation value setting step is performed or a latest random number having a length equal to the operation length is set as the seed.
