Which is true about secure crypto key distribution?

• A. How to securely distribute keys
• B. The color of hardware tokens
• C. The hours of key management staff
• D. The encryption algorithm used for data

Answer: (A)

Secure crypto key distribution focuses on how cryptographic keys are moved between systems and people without exposing them. The statement about securely distributing keys is the best fit because it directly addresses protecting keys during transfer, ensuring confidentiality and integrity as they move from one point to another. In practice, this means using encrypted and authenticated channels, such as TLS or PKI-based exchange, applying key wrapping, and leveraging secure hardware like HSMs, along with controls like dual control and audit logs to prevent unauthorized access.

The other factors don’t address the transfer process. The color of hardware tokens has no impact on security, and the hours of key management staff don’t define how keys are protected in transit. While the encryption algorithm used for data is important for protecting the data itself, it doesn't specify how the keys used to perform that encryption are distributed securely.
