16.3.4. Key Distribution Problem

Try these first

1. 1.

   Define public key cryptography.

   Hint

   Think about how public and private keys function together.

2. 2.

   Explain the main purpose of the Diffie-Hellman protocol.

   Hint

   Consider how secure communication is established.

3. 3.

   What does the RSA algorithm rely on for security?

   • The difficulty of discrete logarithm
   • The difficulty of factoring large primes
   • The XOR operation

   Hint

   Recall the fundamental principles of RSA.

4. 4.

   True or False: In public key cryptography, the same key is used for both encryption and decryption.

   • True
   • False

   Hint

   Think about how public and private keys function.

5. 5.

   Describe a scenario where public key cryptography would be preferred over symmetric key cryptography. Discuss the reasons for your choice.

   Hint

   Think about secure online communications.

6. 6.

   Explain how the security of the RSA algorithm could be compromised with current technological advancements.

   Hint

   Consider hypothetical future technologies.
