The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

Diffie-Hellman Key Exchange is used for securely sharing a secret key between two parties over an insecure channel. Initialization: Agree on a large prime number ( p ) and a primitive root ( g ) ...

Each party selects a private key and calculates their public key using the formula ( g^{\text{private key}} \mod p ). Each party then shares their public key with the other. Secret Key Computation: ...

Abstract: Secure communication in a wireless system or end-to-end communication requires setup of a shared secret. This shared secret can be obtained by the use of a public key cryptography system.
