Method and apparatus for generating pseudo-random number using non-linear function

摘要

The present invention relates to a method for generating a pseudorandom number required for generating keys of various systems requiring high security, and a conventional pseudorandom number generating method has a problem that a short periodicity is found or a lot of time is required for random number generation . Therefore, a physician using a nonlinear function that generates a chaotic function by a nonlinear function library and generates a random number that is very sensitive to initial values and very difficult to find the periodicity is selected by selecting the result of the chaotic functions using a random number And to provide a random number generating method and apparatus.
