WebJul 18, 2024 · Definition: Diffie-Hellman Key Exchange. The following protocol is called Diffie-Hellman key exchange [ DHKE ]: Alice and Bob agree upon a large prime p and a primitive root r ∈ ( Z / p Z) ∗ and publish both. Alice chooses an α ∈ Z satisfying 1 ≤ α ≤ p − 1, computes A = r α ( mod p), keeps α secret, but publishes A.
