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.
