Whitfield Diffie and cryptologist Martin Hellman together coined the term Diffie-Hellman key exchange to provide a sound mechanism for cryptography. Read: Data Science vs Data Analytics Where Did The Diffie Hellman Key Exchange Come From? The algorithm provisions safely create a shared key on a secure channel and even over an insecure channel tracked by the adversaries. This issue can be handled easily with the Diffie Hallman key exchange, which makes this method unique. If the encryption is done on the message, no one will be able to read it. Messages sent without encryption can make any undesirable person read the contents. There is no secure channel to talk to them. You want to communicate with a spy from an allied nation who is not known to you. Let’s understand the mechanism with the following example, It set a milestone in cryptography and is still used today in various applications where encryption is required. The Diffie Hellman key exchange method was first used to develop and exchange keys over an insecure channel safely. What is the significant feature of the Diffie Hellman exchange?.How and where is Diffie Hellman Key Exchange?.How Is The Diffie-Hellman Key Exchange Implemented?.How does the Diffie-Hellman Key Exchange Mechanism Work?.Where Did The Diffie Hellman Key Exchange Come From?.These signify the message verification, no change in the message content, and ensure that the sender cannot deny sending the message. The algorithm provides confidentiality and drives key security initiatives such as authentication and integrity. It is also called an exponential key exchange, is a digital encryption method that produces a decryption key with numbers raised to specific powers depending on the non-transmitted components. One such algorithm that has been popularly used by the industries is the Diffie Hellman key exchange. The modern algorithms have replaced the outdated data encryption standard (DES) and play a crucial role in IT systems’ security. The main aim of encryption is to protect the digital data stored on computer systems. It is one of the most secure methods used widely for encrypting the data.
