1. 1.

   What is the main purpose of the Diffie Hellman protocol?

   Hint

   Think about the type of communication it enables.

2. 2.

   Who are the two roles in the Diffie Hellman exchange?

   Hint

   Recall the example used in the lecture.

3. 3.

   What is the function of the Diffie Hellman Key Exchange Protocol?

   • To encrypt data
   • To securely exchange cryptographic keys
   • To decrypt data

   Hint

   Consider the goal of the communication process.

4. 4.

   True or False: The Diffie Hellman protocol requires both parties to be online at the same time to exchange keys.

   • True
   • False

   Hint

   Think about the effect of time zones on communication.

5. 5.
