Which statement about Link 16 security and protection is most accurate?

• A. Encryption, ECCM, and frequency hopping collectively reduce interception risk and improve resilience to jamming.
• B. Security is achieved solely by encryption.
• C. There is no security requirement for Link 16.
• D. Frequency hopping alone ensures complete security.

Answer: (A)

Security in Link 16 comes from layering protections that address different threats. Encryption guards the content so captured messages remain unread. ECCM helps keep the link alive and accurate even in the presence of jammers or deceptive signals. Frequency hopping spreads the signal across many frequencies, making interception harder and making it more difficult for a jammer to stay effective. Together, these measures reduce interception risk and improve resilience to jamming. Relying on encryption alone misses anti-jamming benefits, while frequency hopping alone doesn’t protect the message content or counter EW effects; there is indeed a security requirement for Link 16.
