What is a quantity of keying material, not yet effective, held in reserve by an account for use at a later date called?

• A. Reserve On Board (ROB)
• B. Future Key Reserve
• C. Pending Key Stock
• D. Deferred Key Material

Answer: (A)

In key management, when cryptographic material is prepared but not yet active, it is stored as a Reserve On Board. This means the keying material is kept secure on site and scheduled to become effective at a future date. Maintaining a Reserve On Board ensures there’s a ready supply of keys to activate when current keys lapse or need replacement, preventing gaps in cryptographic support. The other terms don’t reflect that combination of being stored on site, reserved, and not yet active, so they don’t fit the standard usage.
