Dynamic Matrices from Hardware Fingerprint and Its Application in Software Copyright Protection

This paper presents a scheme of software copyright protection based on dynamic matrices from hardware fingerprint and user’s information. It is mainly as follows. (1)Introduces the basic idea of software copyright protection; (2)Introduces the alphabetic operation of field F37; (3)Uses hardware fingerprint and user’s information to create dynamic matrices to design an affine mapping of F37 to generate a registration code; (4) Uses the invert mapping to verify a registration code. (5)Gives concrete examples. Data and keys are used in a way to prevent sharing registration code with any other computer. The text submitted to the vendor by the user is not the source plaintext for the registration code. Real plaintext is hidden in the software, unknown to the outsiders. It is deceptive to possible adversaries. Attacks for a legal registration code from the submitted text will not success. Experimental results and analysis illustrate the algorithm viable and secure.
