Preparing and loading the code requires the developer to perform several steps:

1. The developer selects arbitrary code in accordance with the task being solved and taking into account the recommendations of Guardant.
2. The loaded code is ported to the C language and converted for use in the hardware key. At this stage, it is possible to embed the use of built-in key functions into the code: call cryptographic algorithms, perform time licensing (for Time keys), write/read data in memory cells, and others.
3. With the help of the GCC compiler and the Guardant SDK utilities, the loaded code is assembled and written to the key memory.
4. After that, the loaded code can be used from a secure application by simply calling the Guardant API functions. In fact, the program code and the key become one.

The final application protection scheme depends on the specific task. However, the basic principle can be represented as follows:

• The application is "binded" to the license using automatic protection tools, downloadable code and a special API;
• The license is securely stored in the key memory;
• During operation, the protected application constantly exchanges information with the key. If the key is missing or includes unsuitable or expired license, then the software does not work.

Thus, copying a protected program makes no sense, since without a key it becomes inoperable.
