Diffie-Hellman

Definition

Diffie-Hellman is a cryptographic protocol that allows two parties to establish a shared secret key over an insecure communication channel. This key can then be utilized to encrypt subsequent communications, ensuring their confidentiality. It constitutes a foundational element of many contemporary cryptographic systems, including those securing internet traffic. The protocol itself does not confirm the identities of the parties, necessitating additional mechanisms for identity validation.
