A family of cross-platform keys for licensing, protection and management of hardware and software product sales. Satisfies the maximum security requirements due to code execution directly inside the protected device.
List of solutions, that include the product
Advantages
Codeinside
Allows executing part of the code directly inside the dongle to protect mechanisms and provide secure licensing
Cross-platformness
Ensures the operation of the key in any operating system and on any device equipped with a USB interface
Protected memory
Prevents unauthorized reading of the license, calling the downloaded code and analyzing the logic of the key operation at the hardware level
Remote update mechanism
Allows to remotely update the license and downloadable code in the key without the possibility of substituting their data
Secure exchange protocol
Uses encryption based on unique session keys when transferring data between the application and the hardware key

Key operation scheme
Using the downloadable code
Preparing and loading the code requires the developer to perform several steps:
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.
Application protection scheme
The final application protection scheme depends on the specific task. However, the basic principle can be represented as follows:
Thus, copying a protected program makes no sense, since without a key it becomes inoperable.
