Electronic Key Management System - Tier 3

Tier 3

The lowest tier or layer of the EKMS architecture which includes the AN/CYZ-10 (Data Transfer Device (DTD), the SKL (Simple Key Loader) AN/PYQ-10, and all other means used to fill keys to End Cryptographic Units (ECUs); hard copy material holdings only; and STU-III/STE material only using Key Management Entities (KMEs) (i.e., Local Elements (LEs)). Unlike LMD/KP Tier 2 accounts, Tier 3 using entities never receive electronic key directly from a COR or Tier 0.
