Implementing Cisco Secure Mobility Solutions (SIMOS, legacy) — Question 39

In the Diffie-Hellman protocol, which type of key is the shared secret?

Answer options

• A. a symmetric key
• B. an asymmetric key
• C. a decryption key
• D. an encryption key

Correct answer: A

Explanation

The correct answer is A, as the shared secret in the Diffie-Hellman protocol is a symmetric key that both parties use for encryption and decryption of messages. Options B, C, and D are incorrect because an asymmetric key refers to keys used in asymmetric encryption, and decryption or encryption keys do not specifically describe the shared secret in this context.
