V-Clock Module

V‑Clock is a virtual clock that is available in Sentinel SL keys and in all Sentinel HL (Driverless configuration) keys except for Sentinel HL Basic keys. V‑Clock is for vendors who want to use time-based licenses to protect their applications but do not want to provide a Sentinel HL Time key or Sentinel HL NetTime key. (These keys contain a real-time clock.)

The use of V‑Clock with Sentinel SL keys and most Sentinel HL keys does not require a special license. However, to generate time-based licenses that depend on V‑Clock in Sentinel HL Pro keys, you must purchase the V‑Clock module for your Sentinel LDK Master license.

For more information on V‑Clock, see How Sentinel LDK Protects Time-based Licenses With V-Clock.

AppOnChip Module

AppOnChip functionality provides significant protection for applications by moving code fragments from the application code to a Sentinel HL (Driverless configuration) key. This creates a strong binding between the protected application and the presence of the protection key, and limits reverse engineering of the protected code to black box analysis only.

The AppOnChip module is not required for applications that are licensed using Sentinel HL Max, Time, NetTime, Net, and Drive keys. For applications that are licensed using Sentinel HL Basic keys or Sentinel HL Pro keys, an annual or perpetual AppOnChip module must be obtained from Thales.

The AppOnChip module is typically placed on your Developer key. (For details, see Updating the Master License.) The key that contains the AppOnChip license must be connected to the machine where Sentinel LDK Envelope or Sentinel Data Protection utility runs.
