Which cryptographic standard is used to secure FSM communications?

• A. KG-175
• B. KG-226
• C. AES-256
• D. DES

Answer: (A)

Securing FSM communications relies on a standardized cryptographic solution that combines strong encryption with built-in key management in hardware. KG-175 is a DoD/NSA-standard cryptographic device family designed to protect communications between field systems, providing certified, interoperable protection for data in transit and the keys that guard it. This integrated, hardware-backed approach is essential because encryption alone isn’t enough without proper key handling and secure channel management. DES is outdated and vulnerable due to its short key length, making it unsuitable for modern FSM links. AES-256 is a strong algorithm, but on its own it doesn’t define the secure channel standard or the hardware, interop-friendly framework used for FSM communications. KG-226 is a different device family and serves other roles or platforms; the established standard for securing FSM communications in this context is KG-175.
