Question 2.
Define plaintext.
Show hintHide hint
Consider the message before it gets scrambled.
3Question 3.
What is the role of the symmetric key in encryption?
- To encrypt only
- To decrypt only
- For both encryption and decryption
Show hintHide hint
Consider who has the key.
4Question 4.
True or False: In symmetric key encryption, the same key is used for both encrypting and decrypting.
- True
- False
Show hintHide hint
Think about how Sita and Ram handle their messages.
Question 5.
How would an attacker try to break the symmetric encryption? Discuss the techniques they might use and suggest ways to strengthen the key agreement process.
Show hintHide hint
Think about common ways attackers exploit weaknesses.
Question 6.
Consider a scenario where Sita and Ram set their symmetric key as '12345'. Discuss the implications of using such a weak key. What would be a better approach?
Show hintHide hint
