NETWORK SECURITY - DIFFIE HELLMAN KEY EXCHANGE ALGORITHM

Описание к видео NETWORK SECURITY - DIFFIE HELLMAN KEY EXCHANGE ALGORITHM

This Algorithm is used to exchange the secret /symmetric key between sender and receiver.
This exchange of key can be done with the help of public key and private key

step 1 Assume prime number p
step 2 Select a such that a is primitive root of p and a less than p
step 3 Assume XA private key of user A
step 4 Calculate YA public key of user A with the help of formula
step 5 Assume XB private key of user B
step 6 Calculate YB public key of user B with the help of formula
step 7 Generate K secret Key using YB and XA with the help of formula at Sender side.
step 8 Generate K secret Key using YA and XB with the help of formula at Receiver side.
