WebFeb 28, 2024 · The steps needed for the Diffie-Hellman key exchange are as follows: Step 1: You choose a prime number q and select a primitive root of q as α. To be a primitive root, it must satisfy the following criteria: Step 2: You assume the private key for our sender as Xa where Xa < q. The public key can be calculated as Ya = αxa mod q. WebApr 12, 2024 · The classical key pair is called ephemeral in Unified Diffie-Hellman since it is a temporary key pair used only for the current exchange. The signing key pair is the static pair. The public portion of the signing key can be published in a common directory for convenient access since the signing key pair changes infrequently.
