Diffie$-$Hellman Algorithm and Encryption

Please describe $$Diffie $-$Hellman rounds for four participants:

assign a private key to each participant,$$

use the same one$-$way function as in the handout and$$

design the protocol $($who is sending a number to whom$).$

At the end of the fourth round, all participants are supposed to arrive at the same number$$convert this number to binary.

Use this binary number as a key for XOR Encryption. Encrypt your name $($maybe a shorter version$).$
