Diffie–Hellman (DH) key exchange is a mathematical method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman.

O método da troca de chaves de Diffie-Hellman permite que duas partes que não possuem conhecimento prévio uma da outra, compartilhem uma chave secreta sob um canal de comunicação inseguro. Tal chave pode ser usada para encriptar mensagens posteriores usando um esquema de cifra de chave simétrica.
Elliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel.
Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key.
The Diffie-Hellman key exchange (sometimes called an Exponential key exchange) is a protocol used to secretly share information with keys. Background. In 1976, Whitfield Diffie and Martin Hellman invented a way for people to encrypt data and send it over an open channel. The idea was based on a concept by Ralph Merkle .
The Diffie–Hellman problem (DHP) is a mathematical problem first proposed by Whitfield Diffie and Martin Hellman in the context of cryptography and serves as the theoretical basis of the Diffie–Hellman key exchange and its derivatives.
24 de nov. de 2013 · Diffie-Hellman is a way of generating a shared secret between two people in such a way that the secret can't be seen by observing the communication. That's an important distinction: You're not sharing information during the key exchange, you're creating a key together.
