List of solutions, that include the product
Mobile applications
Advantages
Loadable code assumes an entry of an arbitrary executable code in the key for protection of valuable algorithms and creation of own licensing mechanisms
Integrated flash memory provides the ability to distribute the software product and content directly in the key
Built-in cryptoprocessor provides the possibility of using pre-installed cryptographic algorithms to enhance the protection of software products
Models
Guardant SD
A hardware key in a miniature form factor for licensing, protecting and managing sales of mobile Android applications.
Key operation scheme
Application protection scheme
The application is protected by transferring part of the code into the key and then calling it. Preparing and loading a Java applet requires the developer to perform several steps:
1. Selecting an arbitrary code in accordance with the task being solved and taking into account the recommendations of Guardant.
2. Building the loadable code and recording it to the key memory using the SDK from Oracle and Google.
3. Calling the loaded Java applet from the protected application using the Guardant Mobile API functions.
