AppOnChip, our newly launched feature, is another level of protection added to Gemalto’s industry-leading Sentinel Envelope which wraps an application to provide robust IP protection against unauthorized use, distribution, tampering and reverse engineering. AppOnChip facilitates an inseparable binding of the Sentinel hardware key to the application. This fully automated process presents software vendors with a list of functions from their application that contain code blocks that are compatible with the AppOnChip feature. The protected code blocks, encrypted and signed, can then be loaded and executed on the hardware key itself. This additional security measure makes it the most secure software licensing implementation in the market.

Once the AppOnChip feature is enabled within Sentinel LDK the unprotected application will get parsed by AppOnChip to analyze all the supported functions. Code blocks from all or several functions, based on ISV selection, get converted to a form that can then be executed on the key. These converted code blocks are encrypted and signed for security.
When an end user attempts to use the software the execution phase kicks in. The protected software executes normally until it reaches the function protected by the AppOnChip feature of Sentinel LDK. The code flow in the application transfers to the key. AppOnChip dynamically loads and then executes the protected code securely on the key. The results from the executed code are returned back to the application and normal flow continues.
Note: This feature comes at no additional cost for all Sentinel HL Max and higher models.
