Understanding Diffie-Hellman Key Exchange

Diffie-Hellman Key Exchange is a method used to securely exchange cryptographic keys over a public channel. It allows two parties to establish a shared secret key that can be used to encrypt and decrypt messages. This key exchange protocol is widely used in modern cryptography to ensure secure communication over insecure networks.

How Diffie-Hellman Key Exchange Works

The Diffie-Hellman Key Exchange algorithm involves two main steps: key generation and key exchange. During the key generation phase, each party generates a public and private key pair. The public keys are then exchanged between the parties. In the key exchange phase, the parties use their private keys and the received public keys to calculate a shared secret key.

This shared secret key can then be used to encrypt and decrypt messages sent between the parties. The beauty of the Diffie-Hellman Key Exchange lies in the fact that even if an eavesdropper intercepts the public keys exchanged, they cannot easily determine the shared secret key without knowledge of the private keys.
