A random number generating system and its method for generating very irregular random numbers without an increase of a consumed current and an expansion of a chip in size, comprising a random number generator 202 for generating random numbers and a signal line 201 for transmitting data to functional blocks arranged outside the random number generator 202, wherein the random number generator 202 has a first shift register 203, a second shift register 204, and a logic device 205 for executing a logical operation between an output from the first shift register 203 and data transmitted through the signal line 201 and then inputting a result of the operation to the second shift register 204 and generates random numbers by using a data value transmitted to the functional block arranged outside the random number generator 202. |
