Question

One weakness of Diffie-Hellman key exchange protocol is
a. It can be easily broken using brute force attack.
b. It is susceptible to man-in-the-middle attack.
c. The key size is small.
d. None of these.

Answer 1

Answer:

B

Explanation:

It is susceptible to man-in-the-middle attack.

Answer 2

Answer:

The weakness of the Diffie-Hellman key exchange protocol is

It is susceptible to a man-in-the-middle attack.

Option (b)

Explanation:

Diffie-Hellman key exchange protocol is a process where a user can send or receive messages securely through a shared public key. This protocol is used in the field of cryptography.

The major shortcoming of this protocol is that it doesn’t establish an identity for a user which makes the process insecure. Eavesdropper can read the message meant for another person and can modify the message.
