The Diffie-Hellman-Algorithm is essentially a protocol for key exchange. By talking with one other, two parties will generate a shared secret key using this interactive protocol. The Diffie-Hellman algorithm's security is primarily dependent on the difficulty of calculating discrete logarithms. Secure Shell (SSH), Transport Layer Security (TLS) / Secure Sockets Layer (SSL), Public Key Infrastructure (PKI), Internet Key Exchange (IKE), Internet Protocol Security (IPSec), and others employ the Diffie Hellman Algorithm to improve security.
