Type: system
Definition
The KIV-77 is a Common Crypto Appliqué (CCA) used with Identification Friend or Foe (IFF) equipment to provide Mode 4 and Mode 5 cryptographic capability. In practical terms, it’s the Type 1, NSA-certified crypto module that enables secure challenge/response between IFF interrogators and transponders, and it is used to store classified key material. It is also treated as a Controlled Cryptographic Item (CCI) and can be removed from the host equipment for secure handling/storage.
