In this original paper, Diffie and Hellman gave a limited example of a public-key system which is known today as the Diffie-Hellman key exchange. Later, in 1978, Rivest, Shamir, and Adleman  gave a complete example of a public-key system that is popularly known as RSA.
Elliptic-curve Diffie–Hellman - Wikipedia 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. This shared secret may be directly used as a key, or to derive another key.The key, or the derived key, can then be used to encrypt subsequent communications using a symmetric-key cipher. הסבר על תקשורת מאובטחת SSL \ TLS הצפנה\הצפנות RSA ומנגנון Diffe Hellman ללא RSA. ללא השימוש בRSA בתחילת ה Diffe Hellman יכול התוקף לבצע את התהליך הבא: כעת ג’ון מתוחכם יותר, אין RSA ובוב ואליס מתחילים להעביר את התוצאה. אליס ובוב קבוע.

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).
Jul 30, 2012 Diffie Hellman - OpenSSLWiki Diffie-Hellman Standards . There are a number of standards relevant to Diffie-Hellman key agreement. Some of the key ones are: PKCS 3 defines the basic algorithm and data formats to be used.; ANSI X9.42 is a later standard than PKCS 3 and provides further guidance on its use (note OpenSSL does not support ANSI X9.42 in the released versions - support is available in the as yet unreleased 1.0 silverlight - RSA encrypted Diffie-Hellman handshake
What's the difference between the RSA and Diffie-Hellman
Choosing the right public key algorithm: RSA vs. Diffie Both RSA and Diffie-Hellman are public key encryption algorithms strong enough for commercial purposes. The minimum recommended key length for encryption systems is 128 bits, and both exceed that with their 1,024-bit keys. Both were invented in the late 1970s and have yet to be cracked. Diffie–Hellman key exchange - Wikipedia In practice, Diffie–Hellman is not used in this way, with RSA being the dominant public key algorithm. This is largely for historical and commercial reasons,  namely that RSA Security created a certificate authority for key signing that became Verisign. Diffie–Hellman cannot be used to … What’s the difference between Diffie-Hellman and RSA? Dec 23, 2017 PGP vs. RSA: How Are They Different? - Syncsort Blog
