<p>An apparatus and method of generating a harsh function using chaos devices are disclosed. According to the present invention, an input information signal is converted to a real number, and chaos signals modulated by the information signal are fedback to the chaos devices. The chaos signals generated in the chaos devices are converted on a bit-by-bit basis by a bit conversion unit, and a hash vector is operated logically and rotated on the bit-by-bit basis in a hash vector rotation unit by means of the signals converted on the bit-by-bit basis. A comparison unit determines whether other information signals continue to be inputted and outputs the hash vector generated in the hash vector rotation unit as a hash value when the other information signals are not inputted any longer.</p> |
