1. 1.

   What is public key cryptography?

   Hint

   Think about how both keys are used in communication.

2. 2.

   What are the components of the RSA algorithm?

   Hint

   Consider what is needed to create the public and private keys.

3. 3.

   What is the main function of public key cryptography?

   • To encrypt data with a single key
   • To use a pair of keys for secure communication
   • To simplify encryption processes

   Hint

   Consider how the keys work together.

4. 4.

   True or False: The Diffie-Hellman protocol requires both parties to exchange their private keys.

   • True
   • False

   Hint

   Think about what is exchanged in the protocol.

5. 5.

   Design a simple system using public key cryptography for a messaging app.

   Hint

   Think about how users will exchange their keys.

6. 6.

   Evaluate the security of the Diffie-Hellman protocol in a real-world context.

   Hint

   Consider how attackers might intercept communication.
