Which set of items constitutes the loading that must be loaded into the KWR-46 before data reception?

• A. UV, CV, BAV (KEK)
• B. UV, CV
• C. BAV (KEK)
• D. KEK only

Answer: (A)

Preparing the KWR-46 for data reception requires loading all cryptographic materials it will use to decrypt and verify the incoming stream. The unencrypted vector provides the starting values used in the decryption process, the cipher vector defines the encryption parameters for the session, and the BAV contains the actual keys wrapped under a key-encryption key (KEK). The device must have UV and CV to configure the crypto engine and BAV (protected by KEK) to unwrap the working keys. Without any one of these, decryption or authentication cannot proceed, so the full set must be loaded.
