Principles of Sentinel LDK

The strength, uniqueness, and flexibility of Sentinel LDK are based on two primary principles:

>Protect Once—Deliver Many—Evolve Often: The concept of separating the Sentinel LDK engineering and business processes.

>Cross-Locking: The technology that supports the Protect Once—Deliver Many—Evolve Often concept, enabling a protected application to work with either a Sentinel HL key or a Sentinel SL key.

NOTE   In general, references in this guide to protected applications are also applicable to protected data files.
