WebJun 19, 2024 · Diffie-Hellman (DH), also known as an exponential key exchange, was published in 1976. DH key exchange is a key exchange protocol that allows the sender and receiver to communicate over a public channel to establish a mutual secret without being transmitted over the internet. DH securely generates a unique session key for encryption … WebApr 9, 2024 · Another example of using the modulo operator in cryptography is the Diffie-Hellman key exchange protocol, which allows two parties to agree on a shared secret key over an insecure channel. The algorithm works as follows: Choose a large prime number p and a primitive root g of p. Alice chooses a secret integer a and sends g^a mod p to Bob. WebStep 4: Recieving a public key, and generating the final secure key. So, let's suppose your friend sent you their public key call it P. Now you do a modular exponentation, only this time using P as your base instead of g. This new number is your secret key. Your friend will have the exact same key This can be written in JS math as: bothered meme
