Which function is NOT performed by the KEK?

• A. Protecting TEK for transmission
• B. Decrypting all types of data
• C. Securing keying material
• D. Managing cryptographic algorithms

Answer: (B)

The function that is not performed by the Key Encryption Key (KEK) is related to decrypting all types of data. The KEK specifically serves to protect and secure keying material, such as the Transport Encryption Key (TEK), during transmission. It can be used to encrypt and decrypt keys rather than general data. When it comes to managing cryptographic algorithms, the KEK plays a supporting role within the cryptographic framework but does not directly manage algorithms themselves. Overall, while the KEK is a critical component for ensuring the integrity and confidentiality of keying material, its purpose does not extend to the decryption of all types of data, making this function the correct answer.
