In the paper is described a new method of software protection by means of Generalized Net (GN). More specifically, the paper presents a novel application of a GNs concept which is a powerful tool for the representation and handling of dynamic discrete event problems and systems. The article describes a method of software protection which combines anti-debugging and registration number protection techniques. Instead of blocking the debugging tools, the fragment that realizes registration number comparison gets more complicated and integrates a GN into the code in a uniques way. The complex mathematical apparatus of GNs is unknown and difficult to understand by crackers, which increases the reliability of the method. The reliability of the proposed method is also increased by the use of two-factor authentication. The description of the protection method is preceded by a brief introduction to the field of study and to the used apparatus of the GNs theory. The report ends with short notes on the reliability of the method.
Abstract
In the paper is described a new method of software protection by means of Generalized Net (GN). More specifically, the paper presents a novel application of a GNs concept which is a powerful tool for the representation and handling of dynamic discrete event problems and systems. The article describes a method of software protection which combines anti-debugging and registration number protection techniques. Instead of blocking the debugging tools, the fragment that realizes registration number comparison gets more complicated and integrates a GN into the code in a uniques way. The complex mathematical apparatus of GNs is unknown and difficult to understand by crackers, which increases the reliability of the method. The reliability of the proposed method is also increased by the use of two-factor authentication. The description of the protection method is preceded by a brief introduction to the field of study and to the used apparatus of the GNs theory. The report ends with short notes on the reliability of the method.
