In a Diffie-Hellman key exchange setup, Alice and Bob agreed on global/public parameters as follows:

• A prime integer, P = 191
• A primitive root of the prime(q), g = 19

 my ID is 301150681

Furthermore, Alice chooses her random private key X_A= [int (your id /2)] mod 89 and Bob chooses his random private key X_B = [int (your ID /3)] mod 89

 

If X_A, or X_B, becomes Zero then chose a number from the list for X_A, or X_B: [19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151]

 

If X_A, and  X_B, both of them Zero then chose a different number from the list for X_A, or X_B: [19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151]
