What type of crypto is used for FSM?

• A. KG-175
• B. KG-184
• C. KG-188
• D. KG-190

Answer: (A)

In this context, the encryption used for FSM is identified by the hardware crypto module family (KG-series). FSM relies on a Type 1 cryptographic device, and the specific model chosen for that role is KG-175, which is the one configured and approved for FSM’s secure communications.

KG-175 is the model that fits FSM’s required capabilities and key-management interface. The other KG models listed correspond to different devices or capabilities used in other systems, so they’re not the standard crypto for FSM in this scenario. Understanding that the KG family denotes NSA-approved Type 1 hardware crypto helps explain why a particular model is specified for a given system.

KG devices provide encryption and key handling in hardware to meet security levels for classified communications; remembering which model is associated with a system like FSM helps you answer these questions correctly.
