This increases the cost of reversing the program and the anti-analysis ability of the software.
Several obfuscation techniques can be combined to create a layered effect. Moreover, the cyclomatic complexity of the program increases. Obfuscation algorithms are a means of transforming computer programs to make them harder to understand and reverse engineer. As more functions are added, the difference between the obfuscated calling graph and the original calling graph increases. These techniques are widely used to prevent attacks such as MATE and counterfeiting. They are also essential to protect intellectual property. Now that you know more about Skater Today - The Skater .NET Obfuscator, let's talk about obfuscation algorithms. The number of functions in a program determines the strength of the obfuscation effect.

Another technique is a technique called the bogus function calling graph. Because of this, the original version is difficult to interpret with the human eye. This change is very effective because it enables reverse analyzers to face more abstract functional units. This method changes the called function before running the target program. However, this method is easily susceptible to dynamic analysis of the program. In this case, the obfuscated version is influenced by the dynamic analysis, which causes the obfuscated calling relationship to change. COOPS starts from the semantics of the program and transforms it into an interfunction call flow graph. Also, the control flow is critical to determining the intent of the program. If the control flow is not understood, it is difficult to determine the true content of the message.Another technique is the COOPS (Control Flow Oriented Obfuscation Scheme), which changes the control flow structure of the program. Moreover, it improves the resistance of the software against similarity analysis techniques.
It is important to remember that obfuscation algorithms affect the program's semantics as well as the calling relationship.
