Diffie Hellman key exchange Algorithms is developed by Whitefield Diffie and Martin Hellman in 1976 to overcome the problem of key agreement and exchange. It enables the two parties who want to communicate with each other to agree on symmetric key, key can be used for encrypting and decryption, note that Diffie Hellman key exchange algorithm can be used for only key exchange not for encryption …

Diffie-Hellman Key Exchange: The Diffie-Hellmann key exchange is a secure method for exchanging cryptographic keys. This method allows two parties which have no prior knowledge of each other to establish a shared, secret key, even over an insecure channel. The concept uses multiplicative group of integers modulo, which without knowledge of the Diffie–Hellman Key Exchange - Practical Cryptography for Diffie–Hellman Key Exchange (DHKE) is a cryptographic method to securely exchange cryptographic keys (key agreement protocol) over a public (insecure) channel in a way that overheard communication does not reveal the keys. The exchanged keys are used later for encrypted communication (e.g. using a symmetric cipher like AES). Diffie Hellman - Symmetric or Asymmetric — TechExams …

Diffie-Hellman (DH) allows two devices to establish a shared secret over an unsecure network. In terms of VPN it is used in the in IKE or Phase1 part of setting up the VPN tunnel. There are multiple Diffie-Hellman Groups that can be configured in an IKEv2 policy on a Cisco ASA running 9.1 (3). Diffie-Hellman | Brilliant Math & Science Wiki
