What is the function of encryption keys and crypto devices in Link 16?

• A. Increase data throughput.
• B. It improves cryptographic strength post-processing.
• C. To protect confidentiality, integrity, and authenticity of transmitted data.
• D. To coordinate unit movements.

Answer: (C)

Encryption keys and crypto devices in Link 16 are used to guard the information that travels across the network by protecting confidentiality, integrity, and authenticity of transmitted data. The keys determine how messages are encrypted and decrypted, while the crypto devices perform the actual cryptographic operations and manage keys so that only authorized parties can access or verify the content. This combination prevents eavesdropping, tampering, and spoofing, which is essential for secure military communications. Increasing data throughput, post-processing strength, or coordinating unit movements are not the primary purposes of encryption in this context.
