Regаrding Perfect Fоrwаrd Secrecy (PFS), аnswer the fоllоwing 4 questions. 1, Explain what is perfect forward secrecy. For the following 3 communication protocols: first decide if they have Perfect Forward Secrecy? Then, briefly state your reason. If your answer is Yes, this protocol has PFS, explain the reason why. If your answer is No, this protocol does not have PFS, give a example and explain what the attacker can do. 2. Alice and Bob have a shared secret K. Alice generates a random value R and sends (R)K to Bob. Alice and Bob use R as the session key to exchange data and both forget R when the session is finished. 3. Alice and Bob both have a public/private key pair and know each other’s public key. Alice generates a random value R, and send (R)Kb+ to Bob. Alice and Bob use R as the session key to exchange data and both forget R when the session is finished. 4. Alice and Bob both have a public/private key pair and know each other’s public key. Alice generates a pair of public/private keys, K+ and K-, and sends K+ to Bob. Bob generates a random value R, and sends (R)K+ to Alice. Alice and Bob use R as the session key to exchange data and both forget R, K-, and K+ when the session is finished.
