What is the main disadvantage of the Diffie–Hellman key exchange protocol?
- It is computationally inefficient
- It does not provide any privacy guarantees
- It is vulnerable to brute force attacks
- It requires both parties to be available online (correct)
What is the key factor that determines if an eavesdropper can learn anything about the final key in the Diffie–Hellman protocol?
What is the key factor that determines if an eavesdropper can learn anything about the final key in the Diffie–Hellman protocol?
- CDH assumption (correct)
- DDH assumption
- Length of the keys

Why does the CDH assumption play a crucial role in determining privacy in the Diffie–Hellman protocol?
Why does the CDH assumption play a crucial role in determining privacy in the Diffie–Hellman protocol?
- It ensures the security of the encryption keys
- It speeds up the key exchange process
- It prevents adversaries from gaining knowledge of the resultant key (correct)
- It guarantees the confidentiality of the communication
