PIRACY PROOF SYSTEM FOR SOFTWARE USING CHAOS PRINCIPLE

摘要

PURPOSE: A piracy proof system for software using chaos principle is provided to enhance a cryptogram velocity and a decoding velocity. CONSTITUTION: A white color noise generator(100) converts an analogue output creating a white color noise into a digital output and outputs the digital output to a confusion system(110). Thus, a confusion signal similar to a noise signal is generated. The noise signal is mixed with an information signal in a cryptogram module(120), and thus a cryptogram information signal is created. The information signal is mixed with the 8-bit confusion signal by 16-bit, and 24-bit cryptogram information signal is outputted. The signal is traded by storing in a CD or a diskette, and a hardware key lock having the confusion system(110) is provided.
