Q2. Part -1.
This question is about placement of encryption function and key exchange

c.
Discuss Diffie-Hellman key exchange protocols to enable two users to securely exchange a
key that can be used for subsequent encryption of messages.

d.
In Diffie-Hellman key exchange is based on the use of the prime number q = 353 and a
primitive root of 353, in this case α = 3. A and B select secret keys XA = 97 and XB = 233,
respectively. Use this information to compute public key for both sender A and Receiver B.
Once the public key is calculated then compute a common secrete key.
