Sentinel LDK security

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP. Applies only to RIPs using LDK security.

The Harlequin Core security application is the Sentinel License Development Kit (LDK) from Gemalto N.V. This system allows GGSL and you to:

  • Provide a robust security model, from a specialist security company.
  • Enable timely and efficient delivery of RIP licenses to you, allowing flexibility and immediate onward delivery without requiring that you hold large inventories.
  • Allow GGSL to offer security variations as requested by some customers.

The LDK provides intellectual property (IP) protection features with a web-based license management system called EMS, Gemalto's entitlement management system.

When installing Windows LDK-secured HHR, you must install the supplied external License Manager, hasp_rt.exe, in the same directory as an LDK-secured HHR application (either clrip.exe or your own application that links to corelib.dll). Failure to do so results in slow RIP start-up times and possibly other hard-to-diagnose failures.

If you do not have the correct privileges when installing the Host Renderer on Linux the LDK may be loaded onto the machine but not installed. To complete the installation of LDK see Installing or upgrading the Sentinel LDK License Manager Linux.

If the system asks for libXmu components then you would need to install using “sudo yum install libXpm ”.

On Linux, the various LDK utilities require You should check that this is installed. If it is not, you must install it before the ldktool or ldkutil utilities can be run. The required yum package is openssl 1.1.1.

Your LDK key ID is displayed in the command line window when the test harness is used. For more information see the Sentinel LDK Security document.
