PSEUDO RANDOM NUMBER GENERATION DEVICE AND METHOD USING NONLINEAR FUNCTION

摘要

The present invention relates to a method for generating pseudo random numbers required for generating keys of various systems requiring high security, and the conventional pseudo random number generating method has a problem in that a short periodicity is found or a long time is required for random number generation. have. Therefore, a nonlinear function is generated by a nonlinear function library, and the result of the chaotic functions is randomly selected using a random value. The pseudo-value using the nonlinear function makes the random number very sensitive to the initial value and very difficult to find periodicity. To provide a random number generating method and apparatus.
