Diffie-Hellman Example

• Party 1 and 2 exchange P and Q publicly.

• Party 1 computes A* = QA mod(P) for secret A (known only to itself) and Party 2 computes B* = QB mod(P) for secret B. Then they exchange A* and B*.

• The Secret Key is computed by each:

• DHS = (B*)A mod (P)

• DHS = (A*)B mod (P)
