Question

Quizplus · Accepted Answer

The key exchange protocol is vulnerable to a man-in-the-middle attack because it does not authenticate the participants. In this attack, an attacker intercepts the communication between the two parties and impersonates each of them to the other. Thus, the attacker can see all the information exchanged between them and can even modify it. Therefore, it is important to use authentication mechanisms to prevent this attack.
