Challenge Problems

Push your limits with challenges.

Question 1

Consider a scenario where Sita and Ram use a key agreement protocol over an insecure communication channel. Analyze and discuss how an attacker might try to listen in on their conversation and what measures are in place to protect their key exchange.

💡 Hint: Reflect on the security features of the Diffie-Hellman protocol and its reliance on computational difficulty.

Question 2

Research further on the efficiency of the Diffie-Hellman protocol versus other key agreement protocols. What are the advantages and possible disadvantages?

💡 Hint: Compare it against protocols like Rivest-Shamir-Adleman (RSA) in terms of speed and security.
